If a flat rectangular conductor 35 cm long has a mass of 51 g and lies at right angles to a uniform magnetic field of 0.35T. Only 20 cm of the conductor is actually in the magnetic field. Include F net statements and a free body diagram in your answer.
1) Draw the field lines of the external magnetic field
2) According to left hand rule three what is the direction of the force that the conductor is experiencing?
3) What force (direction and size) should be provided to keep the conductor positioned among the magnets when the conductor carries a current of one amp?
