⚙️ Electric Motor:

An electric motor is a device that converts electrical energy into mechanical energy.

Working Principle:

It works on the principle that a current-carrying conductor placed in a magnetic field experiences a force (Fleming’s Left-Hand Rule).

How it Works:

A coil (armature) is placed between the poles of a magnet.

• • When electric current flows through the coil, it experiences a force on both sides.

• • These forces act in opposite directions, causing the coil to rotate.

• • A commutator is used to reverse the direction of current after every half turn to keep the rotation continuous.

Uses:

Electric fans, mixers, washing machines, etc.

⚡ Electric Generator:

An electric generator is a device that converts mechanical energy into electrical energy.

Working Principle:

It works on the principle of electromagnetic induction. When a coil rotates in a magnetic field, a current is induced in the coil.

How it Works:

• • A coil is rotated between the poles of a magnet.

• • As it rotates, it cuts the magnetic field lines and induces a current.

• • Slip rings are used in AC generators to allow current to flow out without changing direction inside the coil.

• • The direction of the current keeps changing, producing alternating current (AC).

Uses:

Power generation in power stations, wind turbines, etc.
