8.The drawing shows a cross section of a long solenoid. The uniform magneticBfield in the interior of the solenoid is B = 0.12 T point upwards. A loop hasbeen drawn such that side ab is inside the solenoid and side cd is outside thesolenoid where B = 0. The height of the loop (length of side cd is l = 0.5 cm.The number of turns of the solenoid coil that thread through the loop is 6.(a)What is the value of 6 Ē • dỉ around the closed loop (i.e. the sumof B · dỉ around the loop a → b → c → d → a)?(b)What is the magnitude of the current flowing in the wire?Xx xxxxXxxxxxx

We can use Ampere circuital law to find the magnetic flux.

3. The thin, uniform rod shown below has negligible mass and and a length of 0.200 m. It is attached to the floor by a frictionless hinge at point P. A horizontal spring with force constant k = 4.80 N/m connects the other end of the rod to a vertical wall. The rod is in a uniform magnetic field of B = 0.340 T directed into the plane of the page. There is a current of /= 6.50 A in the rod, as shown. a. Calculate the torque due to the magnetic force on the rod for an axis at point P. Do this by defining a differential magnetic force on the rod for a differential length dr at an arbitrary distance r from point P. Relate this differential magnetic force to its differential torque at point P. Then sum (i.e., integrate) the contributions from the entire length of the rod to get the total torque on the rod. b. Consider Hooke's Law, which states that the force exerted by the spring when stretched or compressed a length x is Fspring = kx. Now, given that the rod makes an angle of 53.0° with the…
