A single circular loop of wire with radius R carries a large current I, which constrains a proton of mass m and charge e to travel in a small circle of radius r at constant speed around the center of the loop, in the plane of the loop. The orbit radius r is much smaller than the loop radius R. What is the speed fo the proton in terms of the known quantities I, R, r, m, and e (and what approximations, if any, must be made)? If the current was to decrease slowly, would the proton speed up or slow down?

A small circular loop of wire of radius 5.0 cm and resistance R = 9.0 10-4 Ω is centered inside a large circular loop of wire of radius 50 cm (see figure below). The larger loop, which initially carries a current I = 6.5 A, is cut and its current is reduced to zero over a time interval of 1.2 10-6 s. Find the average current in the smaller loop during this time interval. (The magnetic field of the larger...

A circular loop of wire with radius R is in a uniform magnetic field with magnitude B that points in the positive z-direction. The loop is initially in the xy-plane and carries a constant, unknown current. Flipping the loop over requires you to do positive work (W). Determine the current in the loop.

Find the magnetic field at the centre of a circular loop of radius R, which carries a steady current I. Use your result to calculate the magnetic field that the electron produces at the position of the nucleus in a hydrogen atom with the smallest Bohr orbit radius 0.529 Angstroms. Pretend the motion of the electron is classical.
