The magnetic field at the center of a 50-turn coil of radius 15 cm is 0.80 mT. Find the current in the coil.
Answer to relevant QuestionsIn Exercise 30, if you wanted to double the field strength while keeping the current and turn count the same, what would the coil area have to be? A solenoid is 0.20 m long and consists of 100 turns of wire. At its center, the solenoid produces a magnetic field with a strength of 1.5 mT. Find the current in the coil. A circular loop of wire in the horizontal plane carries a counterclockwise current, as viewed from above. (a) Use the right-hand source rule to determine whether the direction of the magnetic field at the center of the loop ...A charge of 0.050 C moves vertically in a field of 0.080 T that is oriented 45o from the vertical. What speed must the charge have such that the force acting on it is 10 N? A student has a bright idea for a generator that apparently generates electric energy without a corresponding loss of energy somewhere else. His suggested arrangement is shown in Fig. 20.31. The magnet is initially pulled ...
