Magnetism requires no contact. It can act at a distance.
Yes - that is false.
That answer is false NOT true.
That answer is false NOT true.
True. when you heat a magnet you are supplying it with energy therefore the dipoles have enough energy to free themselves form their initial order.
False.
is this true or false conduction is heat transfer by direct contact of particles of matter
false
the answer is false Permanent magnets will hold their magnetism for a long period of time. Electromagnets will only remain magnetic as long as current is flowing through them.
no it is not because gravity brings things down to earth and magnetism can push things up.
That answer is false NOT true.
That answer is false NOT true.
I will contact the doctor because i know never one know when the illness come to ours.I would not blame my doctor because it not their false.
