A Solenoid, of length 1.o m, has a radius of 1 cm and has a total of 1000 turns wound on it. It carries a current of 5 A. Calculate the magnitude of the axial magnetic field inside the solenoid. If an electron was to move with a speed of 10 4 m/s along the axis of this current solenoid what would be the force experienced by this electron?

A rectangular conductor LMNO is placed in a uniform magnetic field of 0.5 T. The field is directed perpendicular to the plane of the conductor. when the arm MN of length 20cm is moved towards left with velocity of 10m–1, calculate the emf induced in the arm. Given the resistance of the arm to be 5Ω (assuming that other arms are of negligible resistance), find the value of current in the arm.
