Write out the “brute-force” (exact) expressions for force and torque on a loop 1 in the magnetic field B of loop 2. Write these expressions using magnetic moment of loop 1. Pay attention to the r, r’, … vectors. A magnet (magnetic dipole) tends to align itself parallel to external field. If the magnetic moment is 5 [CGS units] in -z direction and magnetic field is 25 [CGS units] in z direction. What is the value of the torque? Plot the value of the torque as a function of the angle between the m and B vectors.

Expert Solution

Hi,

Hope you are doing well.

We know that Torque on a magnet(magnetic dipole) placed in uniform magnetic field is given by,

or

Where,

is the magnetic moment (Bi-cm²).

is the magnetic field (G).

is the angle between magnetic moment and magnetic field .

Given that,

Magnetic Moment, along -z axis.

Magnetic field, along z axis.

Since the magnetic moment and magnetic field are in opposite direction, Angle between them,

Torque on a magnet(magnetic dipole) placed in uniform magnetic field is given by,

Hope this helped for your studies. Keep learning. Have a good day.

Feel free to clear any doubts at the comment section.

Please don't forget to give a thumbs up.

Thank you. :)

Bycicles convert force into torque (pedal to axis), torque into force (axis to chain using the front gear), force into a torque (chain to back wheel using back gear), and finally, torque into force (wheel on road), and that accelerates the bike. If you make the front gear smaller, is it easier or harder to pedal (explain in terms of forces/torques)? If you make the back gear smaller, is it easier or harder to pedal?
