It is desired to construct a solenoid that will have a resistanceof 5.00 Ω (at 20°C) and produce a magnetic field of 4.00 x10-2 T at its center when it carries a current of 4.00 A. Thesolenoid is to be constructed from copper wire having adiameter of 0.500 mm. If the radius of the solenoid is to be1.00 cm, determine (a) the number of turns of wire neededand (b) the length the solenoid should have.
. Figure 22.62 shows a long straight wire just touching aloop carrying a current I1. Both lie in the same plane. (a)What direction must the current I2in the straight wire haveto create a field at the center of the loop in the directionopposite to that created by the loop? (b) What is the ratio ofI1/ I2that gives zero field strength at the center of the loop?(c) What is the direction of the field directly above the loopunder this circumstance?
A bar of mass 0.2 kg that can slide without friction on a pair of rails separated by a distance,l= 1.20m and located at an inclined plane that makes an angle of 25° with respect to the ground.The resistance of the resistor is R= 1 Ohm and a uniform magnetic field of B=0.5T is directed downward,perpendicular to the ground,over the entire region through which the bar moves.Find the speed the bar slides along the rails
