A magnet is an object that produces a magnetic field and attracts certain materials like iron.
A magnet has two poles - north and south.
Opposite poles attract each other while like poles repel.
Magnets can be natural (lodestone) or man-made (permanent magnets).
Transformer works on the principle of electromagnetic induction to transfer electrical energy between two or more circuits.
Transformers have two coils of wire, known as primary and secondary coils.
When an alternating current flows through the primary coil, it creates a changing magnetic field.
This changing magnetic field induces a voltage in the secondary coil, transferring electrical energy.

A magnetic field is a region around a magnetic material or a moving electric charge within which the force of magnetism acts.
A magnetic field is produced by moving electric charges or magnetic materials.
It exerts a force on other moving charges and magnetic materials within its vicinity.
The strength and direction of a magnetic field can be represented by magnetic field lines.
Examples include the Earth's magnetic field
The laws of resistance describe how the resistance of a material is affected by factors such as length, cross-sectional area, and temperature.
Resistance is directly proportional to the length of the material - longer materials have higher resistance.
Resistance is inversely proportional to the cross-sectional area of the material - larger cross-sectional areas have lower resistance.
Resistance increases with temperature ...
The relationship between current, voltage, and resistance is described by Ohm's Law.
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor.
Mathematically, Ohm's Law is expressed as I = V/R, where I is the current in Amperes, V is the voltage in Volts, and R is the resistance in Ohms.
