Question

What is the magnetic field inside the solenoid?

B =

2)

A rectanglular loop consists of 5 turns of wire carrying a current of 3.4 A. The loop is in the x-y plane, and the direction of flow of the current is shown in the figure. The loop has dimensions a = 3 cm and b = 7 cm. Consider a uniform magnetic field of strength 3.3 x 10-4 T in x, y, or z directions.

%u03C4 =

%u03C4 =

C) If the uniform field of 3.3 x 10-4 T is along the +z axis, find the magnitude of the torque acting on the loop.

%u03C4 =

3)

Two wires are both 22.3 meters in length and carry perpendicular currents as shown the the left. I1 = 4.8 A and I2 = 6.2 A. Points A and B are located an equal distance from both wires with d = 16 cm.

A)

BA=

4)

A proton (mass= 1.7x10-27 kg, charge= 1.6x10-19 C) travelling with speed 107 m/s enters a region of space containing a uniform magnetic field of 1.2 T.

A)

R =

B)

t =

Explanation / Answer

1)we know that

(mv^2/r) = qvB x sinA

or B = (mv/q x sinA)
