Answer :
Charge will build up on the terminals x and y and X is at lower potential than Y.
What is induced emf?
A voltage will be created if the magnetic flux through a coil is altered. The induced emf is the name given to this voltage.
There are two techniques to induce EMF:
- An induced emf is created when a conductor carrying an electric current travels through a magnetic field.
- An induced EMF is created when a magnetic field revolves around an electric field.
In this case magnetic field B is increasing. That induces electromotive force and charge will build up on the terminals x and y and X is at lower potential than Y.
