Review. A particle with a mass of 2.00 1016 kg and a charge of 30.0 nC starts from rest, is accelerated through a potential difference V, and is fired from a small source in a region containing a uniform, constant magnetic field of magnitude 0.600 T. The particle's velocity is perpendicular to the magnetic field lines. The circular orbit of the panicle as it returns to the location of the source encloses a magnetic flux of 15.0 Wb. (a) Calculate the particles speed. (b) Calculate the potential difference through which the particle was accelerated inside the source.
A circular coil of five turns and a diameter of 30.0 cm is oriented in a vertical plane with its axis perpendicular to the horizontal component of the Earths magnetic field. A horizontal compass placed at the coils center is made to deflect 45.0 from magnetic north by a current of 0.600 A in the coil. (a) What is the horizontal component of the Earths magnetic field? (b) The current in the coil is switched off. A dip needle is a magnetic compass mounted so that it can rotate in a vertical north-south plane.
