A kind of new right-hand rule of the present invention substitutes the Buddhist Lay inscription left hand and the right-hand rule, relates to the basic rule of electromagnetics aspect, is a kind of improvement to the Buddhist Lay inscription left hand and the right-hand rule. Originally in the content of high school physics, judged the direction of magnetic field, use Buddhist Lay inscription left-hand rule the acting force of electric current about electromagnetic induction; And during the conductor cutting magnetic line movement, the induct current direction that is produced then will be judged with the Buddhist Lay inscription right-hand rule. This left hand and right hand rule is easy to obscure, and hand will be crooked sometimes and could judge its direction.

Although, it is best to do it subtly in order not to give the answer away to other students! Magnetic Fields Worked example: Using the left-hand rule. Measurement Techniques 2.

Right and Left Hand Rules

Foundation Science for Engineers pp Cite as. In the previous topic we saw how electric current produces motion in a magnetic field. In this topic we shall see how motion in a magnetic field induces electric current. Unable to display preview. Download preview PDF. Skip to main content.

Electro-Magnetic Induction

Teaching electricity and magnetism is complicated by the challenge that the magnetic forces are perpendicular to the motion of the particles and currents. This requires a three-dimensional perspective which can introduce a variable of a "wrong" direction. To prevent errors, let us be "right" and use the right-hand rule. Some would claim that there is only one right-hand rule, but I have found the convention of three separate rules for the most common situations to be very convenient. These are for 1 long, straight wires, 2 free moving charges in magnetic fields, and 3 the solenoid rule — which are loops of current. Calling these "rules" is the right name. They are not laws of nature, but conventions of humankind.

PDF | A left-hand rule for Faraday's law is presented here. This rule provides a simple and quick way of finding directional relationships.

25.3.1 Fleming's Left-Hand Rule

Fleming's right-hand rule for generators shows the direction of induced current when a conductor attached to a circuit moves in a magnetic field. It can be used to determine the direction of current in a generator's windings. When a conductor such as a wire attached to a circuit moves through a magnetic field, an electric current is induced in the wire due to Faraday's law of induction. The current in the wire can have two possible directions. Fleming's right-hand rule gives which direction the current flows.

When using the Right-Hand Rules, it is important to remember that the rules assume charges move in a conventional current the hypthetical flow of positive charges. In order to apply either Right-Hand Rule to a moving negative charge, the velocity v of that charge must be reversed--to represent the analogous conventional current.

In mathematics and physics , the right-hand rule is a common mnemonic for understanding orientation of axes in three-dimensional space. Most of the various left-hand and right-hand rules arise from the fact that the three axes of three-dimensional space have two possible orientations. One can see this by holding one's hands outward and together, palms up, with the fingers curled, and the thumb out-stretched.

In what direction does the force act on the moving electron? This question requires knowlegde of the right-hand rule. Point the fingers of your right hand in the direction of the electron's velocity to the right. Point your thumb in the direction of the magnetic field into the page. Your palm should be facing in the direction of the force on a positive particle.

When a wire carrying an electric current is moved in a magnetic field of a magnet the magnetic field induced by the wire reacts with the magnetic field of the magnet causing the wire to move outwards. Fleming's left hand rule helps you to predict the movement. F irst finger - direction of magnetic f ield N-S.

Also known as the Motor Rule this is a way of determining the direction of a force on a current carrying conductor in a magnetic field. The thumb, the first and the second fingers on the left hand are held so that they are at right angles to each other. If the first finger points in the direction of the magnetic field and the second finger the direction of the current in the wire, then the thumb will point in the direction of the force on the conductor. Fleming's right hand rule for generators shows the direction of induced current flow when a conductor moves in a magnetic field.

Стратмор пожал плечами: - Так или иначе, уже слишком поздно. Он разместил бесплатный образец Цифровой крепости на своем сайте в Интернете. Теперь его скачать может кто угодно. Сьюзан побледнела: - Что. - Это рекламный ход.

Звонок был сделан из страны с кодом один - из Соединенных Штатов. Нуматака удовлетворенно мотнул головой. Хорошая новость.

- Я сказал, что вируса в шифровалке. Тебе надо лечиться от паранойи. В трубке повисло молчание.

Как у всех молодых профессоров, университетское жалованье Дэвида было довольно скромным. Время от времени, когда надо было продлить членство в теннисном клубе или перетянуть старую фирменную ракетку, он подрабатывал переводами для правительственных учреждений в Вашингтоне и его окрестностях. В связи с одной из таких работ он и познакомился со Сьюзан. В то прохладное осеннее утро у него был перерыв в занятиях, и после ежедневной утренней пробежки он вернулся в свою трехкомнатную университетскую квартиру. Войдя, Дэвид увидел мигающую лампочку автоответчика.

Производители программного обеспечения исходят из того, что рано или поздно появятся компьютеры типа ТРАНСТЕКСТА. Технология развивается в геометрической профессии, и рано или поздно алгоритмы, которыми пользуется общество, перестанут быть надежными. Понадобятся лучшие алгоритмы, чтобы противостоять компьютерам завтрашнего дня. - Такова Цифровая крепость.
