Consider the following figure. rl l-'-l (a) A conducting loop in the shape of a square of edge length {7 = 0.300 m carries a current I = 11.8 A as in the figure above. Calculate the magnitude and direction of the magnetic Field at the center of the square. direction (b) If this conductor is reshaped to form a circular loop and carries the same current, what is the value of the magnetic Field at the center? magnitude:iw direction Two long, parallel conductors, separated by 13.0 cm, carry currents in the same direction. The first wire carries a current I1 = 3.00 A, and the second carries I2 = 8.00 A. (See figure below. Assume the conductors lie in the plane of the page.)

The dimensions in the figure are c = 0.100 m, a = 0.150 m, and f = 0.500 m. Find the magnitude and direction of the net force exerted on the loop by the magnetic field created by the wire. direction The magnetic coils of a tokamak fusion reactor are in the shape of a toroid having an inner radius of 0.700 m and an outer radius of 1.30 m. The toroid has 920 turns of large-diameter wire, each of which carries a current of 11.0 KA. (a) Find the magnitude of the magnetic field inside the toroid along the inner radius. T (b) Find the magnitude of the magnetic field inside the toroid along the outer radius.A long solenoid that has 1 030 turns uniformly distributed over a length of 0.380 m produces a magnetic field of magnitude 1.00 x 10 # T at its center.
