Recitation # 9 Magnetic Forces , April 24, 2018 1) Acurrento 6.57 Aina long straight wire produces a magneti from the wire. Find this distance. field of 8.51 ?? at a certain distance 2) Find the magnitude and direction of the magnetic field at the center of a 77-turn circular coil with radius 13.9 cm, when a clockwise current of 2.85 A flows in it. 3) Two long parallel wires carry currents of 3.61 A and 8.19 A. The magnitude of the force per unit length acting on each wire is 525 × 10 s Nrn. Find the separation distance of the wires expressed in millimeter long solenoid contains 877 turns and carries a current of 5.41 A. What is the strength of the magnetic field at the center of this solenoid?
