AP Physics C: E&M
13.3 Induced Currents and Magnetic Forces
13.2 Electromagnetic Induction

| Loop | Width perpendicular to \(\vec{v}\) | Length parallel to \(\vec{v}\) | Total resistance |
|---|---|---|---|
| 1 | \(L\) | \(L\) | \(R_0\) |
| 2 | \(2L\) | \(L\) | \(2R_0\) |
| 3 | \(L\) | \(2L\) | \(2R_0\) |
| 4 | \(2L\) | \(2L\) | \(4R_0\) |
At an instant when each loop has only its leading edge inside the magnetic field region, which of the following correctly ranks the magnitude of the net magnetic force \(F\) exerted on each loop?
