Question 1

A very long thin wire produces a magnetic field of at a distance of from the wire. What is the magnitude of the current?  (μ0 = 4π × 10-7 T ∙ m/A)
◦ 1.0 mA
◦ 3100 mA
◦ 4000 mA
◦ 2.0 mA

Question 2

Three very long, straight, parallel wires each carry currents of 4.0 A, directed out of the page as shown in the figure. These wires pass through the vertices of a right isosceles triangle as shown. Assume that all the quantities shown in the figure are accurate to two significant figures. What is the magnitude of the magnetic field at point P at the midpoint of the hypotenuse of the triangle? (μ0 = 4π × 10-7 T ∙ m/A)



◦ 4.4 µT
◦ 57 µT
◦ 1.8 µT
◦ 18 µT
◦ 130 µT
