A magnetic field will apply a force on a single moving charge, and it will also exert a force on a current on which is a collection of moving charges. The force encountered by a wire of length l ...

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 strip of aluminum foil, a 6V battery, one to four homemade horseshoe magnets, two brass weights and two patch cords. What it does: When conducting, the aluminum foil strip ‘jumps’ up or ...

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 ...

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 ...

What Is The Hall Effect? Discovered by Edwin Hall in 1879, the Hall effect is a phenomenon when voltage (potential difference) is generated across a current-carrying conductor when it is placed in a ...
