Question

this bar is 0.12 meters long and moving 29.6 m/s through a magnetic field of 58 mt. what is the induced electromotive force in the bar?

Answer 1

The induced electromotive force in the bar is 0.206 volt.

What is induced electromotive force?

It is the creation of a potential difference in a coil as a result of variations in the magnetic flux flowing through it. To put it another way, it is said that electromotive force, or EMF, is induced when the flux connecting with a conductor or coil changes.

Given parameters:

Length of the bar: l = 0.12 meter

Speed of the bar: v = 29.6 m/s.

Magnetic field: B = 58 mT = 58 × 10⁻³ T.

Hence,  the induced electromotive force in the bar: ε = lvB

= 0.12 × 29.6 × 58 × 10⁻³ Volt

=0.206 volt.

Hence, the induced electromotive force in the bar be 0.206 volt.
