The sketch at the left shows a square loop of wire. Its resistance is 5 ohm. Its dimensions are shown: a = 4.0 cm, b = 5.0 cm. The nearby wire carries a current of 10.0 A.
a) What is the magnitude of the magnetic flux in the loop of wire?
b) Is the flux into or out of the page? the loop is b across the top and bottom, a on the sides and is located 2 cm above the wire with current I wich flows to the left
