Question

two wires are perpendicular to the page with current out of the page. we have a 10 amp wire and a 20 amp wire . the wires are separated by 5 centimeters . calculate the location of a point between the wires where the total magnetic field is zero.
Choose the best answer * can't not have zero magnetic field between the wires * 2 centimeters from the 10 amp wire * 1.5 centimeters from the 10amp wire * 1 centimeters from the 10 amp wire * 2.5 centimeters from the 10 amp wire two wires are perpendicular to the page with current out of the page. we have a 10 amp wire and a 20 amp wire . the wires are separated by 5 centimeters . calculate the location of a point between the wires where the total magnetic field is zero.

Explanation / Answer

F1 = F2

uoI1I2/2pir = uoI1I2/2pi(d-r)

1/r = 1/(d-r)

d = 5 cm

r = (d-r)

d = 2r

r = d/2

r = 5/2 = 2.5 cm

2.5 centimeters from the 10 amp wire
