It Is desired to construct a solenoid that will have a resistance of 5.25 (I (at 20°C) and produce a magnetic ?eld of 4.00 x 10'2 T at Its center when it carries a current of 3.00 A. The solenoid is to be constructed from copper wire having a diameter of 0.500 mm. If the radius of the solenoid is to be 1.00 cm, determine the following. (The resistivity of copper at 20°C is 1.7 x 10—8 ? - m.) (a) the number of turns of wire needed to build the solenoid turns (b) the length the solenoid should have cm
The figure below shows a bar of mass m = 0.245 kg that can slide without friction on a pair of rails separated by a distance { = 1.20 m and located on an inclined plane that makes an angle 0 = 32.0 with respect to the ground. The resistance of the resistor is R = 1.80 0, and a uniform magnetic field of magnitude B = 0.500 T is directed downward, perpendicular to the ground, over the entire region through which the bar moves. With what constant speed v does the bar slide along the rails? m/s B
A square coil of wire of side 3.60 cm is placed in a uniform magnetic field of magnitude 2.50 T directed into the page as in the figure shown below. The coil has 36.0 turns and a resistance of 0.780 0. If the coil is rotated through an angle of 90.0 about the horizontal axis shown in 0.335 s, find the following. Rotation axis (a) the magnitude of the average emf induced in the coil during this rotation mV "b) the average current induced in the coil during this rotation MA
