1.8 cm P 2.5 cm The diagram shows two long straight wires carrying the following currents in the directions shown: 119.3 A 12 12.3 A The net magnetic field at P, which is 1.8 cm from 11 and 2.5 cm from 12, is the vector sum of the fields from both wires. Calculate the magnitude of the net magnetic field at P. (Give your answer in tesla but don't include the units)
The magnitude of the magnetic field at the center of a 29-turn loop of wire is 3.7 x 10-6 T. Calculate the current in the loop if the radius is 19 cm. (Give your answer in amps but don't include the units.)
