Answer 1

Answer:

_____________________________________

➡ A current carrying conductor placed within a magnetic field will experience a magnetic force.

______________________________________

Explanation:

➡The working of all electric motors is based on the principle that..... a current carrying conductor placed in a magnetic field will experience a magnetic force.

➡ The force produced in the process rotates the motor and hence play a crucial role in working of electric motors.

Answer 2

The basic principle that enables all the electric motors to operate is that a current-carrying conductor placed within a magnetic field will experience a magnetic force. (Option d)

• In any electric motor, there is a coil made up of a conductor, and the current is passed through it.
• Due to the magnetic field, the coil rotates and generates a force which is then used by the device to operate.
• This rotation converts electrical energy into a mechanical form to be utilized by devices.
• This principle is essential for devices like refrigerators, fans, computers, etc.
