Solve the following problems using the GRESA format: 2. A straight, flexible length of copper wire is immersed in a magnetic field that is directed into the page. (a) If the wire’s current runs in the +x-direction, which way will the wire bend? (b) Which way will the wire bend if the current runs in the –x-direction?   3. A circular coil of current I=1A and area A=0.2m2 is placed flat on a table where the magnetic field B= 1T along the horizontal and to the right, Seen from above and looking down on the table, the current is flowing in a counter clockwise direction. Find the following: a.) Calculate the torque on the coil for N=1 b.) What is the torque on the coil when the coil has turned by 30° c.)  What is the torque on the coil when the coil is perpendicular to the field lines?
