Is it possible to increase an electromagnet's size without changing its input to get the same magnetic field, force, as before?
Example:
Used 1W for an electromagnet with an area of 0.5"x0.5" can pull with 2N At 3V and 0.33amps,
Can I get another electromagnet the same in everything BUT THE...
If there is an electromagnet and a magnet system
Where the electromagnet is fixed and the magnet can move freely with low friction.
The gap between the two is 0. The orientations set-up in a way, that they repel each other,
Now I understood that EMF is generated when there is a "change" in the...
I have two magnets, each capable of attracting/repelling with 10N,
when they are attracted, is the force between them 20N? Since each magnet is applying a force?
Does it take 20N to attract them and 20 to split them apart?
I think the attraction force is greater than the repulsion force, I...
