A 3.0 cm wire carrying a current of 10 A is placed inside a solenoid perpendicular to its axis. The magnetic field inside the solenoid is given to be 0.27 T. What is the magnetic force on the wire?

How is the magnetic field inside a given solenoid made strong?

Choose the correct option The magnetic field inside a long straight solenoid carrying current

A circular loop of radius R carrying a current is placed in a uniform magnetic field with its plane perpendicular to B. The force on the loop is

A long solenoid with 15 turns per cm has a small loop of area 2.0 cm^2 placed inside the solenoid normal to its axis. If the current carried by the solenoid changes steadily from 2.0 A to 4.0 A in 0.1 s, what is the induced emf in the loop while the current is changing?
