Define electromagnetic induction.
Electromagnetic Induction is a process in which an electromotive force (e.m.f.) is induced in any conductor whenever there is a change in the magnetic flux linkages through the conductor.
Define induced magnetism.
Induced magnetism occurs when a magnetic material is placed near to, or touching, any pole of a permanent magnet, thereby becoming an induced magnet itself.
Once removed from permanent magnet, induced magnet will lose its magnetism.
Define light-dependent resistor.
A light-dependent resistor (LDR) is a type of transducer which responds to a change in light intensity. Its resistance decreases when light intensity increases, and vice versa.
Define transducer.
A transducer is an electrical device which can convert energy from one form to another.
Define Ohm’s Law.
Ohm’s Law states that the current through a metallic conductor is directly proportional to the potential difference across it, if the temperature is constant.
Define resistance.
Resistance is the ratio of the potential difference applied to the current flowing through.
