Question

Two wires are placed parallel to each other as shown. They carry currents of 20 A and 5.0 A respectively in opposite directions. The wires are separated by 0.50 m. mc005-1.jpg (a) What is the strength of the magnetic field at a point midway between the two wires? (LaTeX: \mu_0 μ 0 = 4LaTeX: \pi π × 10-7 T · m/A) (b) What is the magnitude of force per length between the two wires?

Answer 1

Oriven, I = 20 A I2 = .00 Separation between the Dires, 70 = 0.50 m field strength at the middle due to current flowing in opposite direction is, a lo'ſ (211) 212 L - a B = 1 1 1 (8/2) i + (7/2) ( ceny na 4 + Foto 415x10t HIT 4x5.0 LT : 57 0.50 - 2 х 10" S Tesla B = 2x 10-5 Tesla length between een се . by of Magnitude of force per unit the wires is, F Mo 21, 12 30 HTX 107 12x 20x 5.0 Nml EX I 0. 50 LITY - / = 4x10-5 Nm
