Magler Train: This train is based on the Lenz law and phenomena of electromagnetic induction. In this there is a coil on a railway track and magnet on the base of train. So as train is deciated then as is move down coil on track repel it and as it move up then coil attract it.
Disadvantage of magler train is that as it slow down the force decreases and as it moves forwatd so due to Lenz law coil attract it backward.
Due to motion of train current induces in the coil of track which levitate it.
Which force causes the train to elevate up
A. Electrostatic force
B. Time varying electric field
C. magnetic force
D. Induced electric field
