Magnetic force is a no work force. Why is it doing work here?
Here the rod is projected with a velocity $v_0$ . Due to change in flux in the loop, we have an induced emf in the loop, which induces a current $i$ that exerts a force $Bil$ where $B$ is the magnetic ...

Find the work to move a coil in an uniform magnetic field [closed]
we have a rectangular coil ($d$ and $3d$ wide) in a magnetic field as in the picture.
To the left we have $B_0 T$ and to the right $\frac{B_0}{2} T$.
There is a counterclockwise current in the coil ...

Why isn't Magnetic force doing any work on the rod?
Consider the situation given below :
The rod (of length $l$ and of some resistance "r") connecting the two rails is given a velocity $v$ in the direction shown. Now since this motion ...

Magnetic Forces and Junkyard Magnets: What's Going On? [duplicate]
In my electromagnetic theory class, I learned that magnetic forces do no work. This is easy to see when observing a cyclotron; the speed never changes, so the kinetic energy never changes and ...
