A technician is working on an MRI machine. To test it, the technician turns on the MRI machine that produces a strong magnetic field, but then he accidentally drops a screwdriver in this magnetic field. As the screwdriver falls, an emf is induced across the length of the metal shaft, L, of the screwdriver. At one instant, the screwdriver falls...

• An electron, at rest, is accelerated through region 1, which has a 5000 V potential difference. It then enters region 2 where there is only a uniform magnetic field and it undergoes uniform circular motion (in a plane) of radius 0.954 mm. After subtending half a circle, the electron exits region 2, traveling in the opposite direction it was...

1. A charge is moved from one point to another in an electric field. Explain briefly the relationship between electric potential difference and work done in moving this charge? 2. what determines the direction of magnitude force acting on a moving charge? When is the magnitude of the magnetic force zero?
