Question

What does a large value of relative permeability mean for a solenoid core?

Options

• The magnetic dipoles must remain in random orientation.

• The material prevents magnetic intensity from being produced.

• The magnetic induction must be zero.

• The material greatly enhances the magnetic field inside the solenoid.

Answer 1

A large relative permeability means the core material greatly enhances the magnetic field inside the solenoid. This is why magnetic cores are used in electromagnetic devices.
