Faraday's Law of Induction Quiz

Faraday's Law of Induction

• An electric current is induced in a coil whenever the number of magnetic lines of force passing through the coil changes.
• The current produced in the coil due to induction is called the induced current.

Direction of Induced Current

• Fleming's right-hand rule is useful to show the direction of the induced current.
• The induced current in the electrical conductor (coil) will be maximum when the direction of motion of the electric conductor is perpendicular to the magnetic field.

Solenoid Coil and Induced Current

• When a current passing through the solenoid coil is increased or decreased, an electromotive force (EMF) is induced in the coil.
• If a current is switched on or off in the solenoid coil, a current is induced in the coil.

Fleming's Right-Hand Rule

• Fleming's right-hand rule helps determine the direction of the induced current.
• To show the direction of the induced current, the thumb, index finger, and middle finger are stretched in a way that they will be perpendicular to each other.

Faraday's Law of Induction in Action

• Current is induced in the coil when it is moved aside from in front of the solenoid due to the change in the number of magnetic lines of force passing through the coil, which is in accordance with Faraday's law of induction.
• When the solenoid coil is displaced longitudinally with respect to the coil, the direction of the magnetic field and the motion of the conductor determine the direction of the induced current.
