1) Which of Maxwell's equations below predicts an induced magnetic field due to changes in an electric field? A) #Edi = 9 B) B. dA= 0 D$B.ds = Hole + Hope E) All of them 2) In the figure, two parallel wires carry currents of magnitude / as shown. The current is decreasing with time. A rectangular loon is midway between the wires. What is the direction of the net magnetic field in the region between the wires and that...
Two straight parallel wires, running north/south are separated by 12 cm and carry currents of 4 A in the same direction (north). Find the magnitude and direction of the magnetic field at a point midway between the wires. Now find the magnetic field 6 cm east of the "easternmost" wire. Also, calculate the force of one wire on the other. Is it attractive or repulsive?
The magnetic force would be zero if:
v was parallel to the field;
v was directed out of page;
v was directed into the page
v=0;
A and D;
B and C
Final result too, please
