Magnetic effect of electric current is one of the major effects which functions as the basic principle in appliances used in various fields of activities. The magnetic field around a current carrying ...

Equipment: A compass, iron filings, a current carrying conductor and a 40 Amp power supply. What it does: The compass shows the direction of the field lines around the conductor. The iron filings line ...

Fleming’s Left Hand Rule can be used to determine the direction of the force, current or magnetic field. This force forms the basis of the electric motor. A current carrying conductor creates its own ...

In modern industry and daily life, motors (or electric motors) are everywhere. From cars to high-speed trains, from fans to household appliances, motors play a crucial role as key devices that convert ...

GK Questions with answers on Science Physics (Magnetic field of electric Current) Set III ,in this set you will find repository of 10 Objective Type Questions that will help you to attune and equipped ...

Using a laser to stimulate a photocurrent and a magnetic field to control it, researchers have devised a scheme for measuring a current’s flow stream. Why there’s a need to assess current-flow ...

In 1831, Michael Faraday discovered that subjecting a coil to a moving magnetic field induces a current. Today, electromagnetic induction powers most electric motors, along with a phenomenon described ...

While many instruments are available to accurately measure small DC currents (up to 3 A), few devices are capable of accurate measurements (better than 1%) of DC currents in ranges that extend beyond ...
