6. Abdul moves a magnetic toy train away from a magnet that cannot move. What happens to the potential energy in the system of magnets during the movement?
a
The potential energy decreases because the train moves in the same direction as the
magnetic force.
b
The potential energy decreases because the train moves against the magnetic force.
С
The potential energy increases because the train moves against the magnetic force.
d
The potential energy does not change because the magnets in the system do not change.
Yeah

coil wire, increase current, put iron inside the coil

are there options? cause you ain’t. real specific

u can delete ur account.

1. go on google and write

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
