Problem: The magnetic field strength at the north pole of a 2.0-cm-diameter, 8-cm-long Alnico magnet is 0.10 T. To produce the same field with a solenoid of the same size, carrying a current of 2.5A,
Part A- how many turns of wire would you need?
Please explain the equations and steps are used to get the answer. Thanks!
A particle having an electric charge q = 3.20 x 10-19 C is injected into a magnetic field B = 0.44 T with a speed of 1.61 x 107 meter per second. Determine how great an electric field would be required to exert an electrostatic force with the same m..
