What's the difference between an electric field and magnetic field?
I dont understand that because a charged particle is moving the force changes. this doesn't work with gravity. If the earth relative to you, the force is still considered gravity. Does a magnetic field always attract or repel other magnetic fields? Also. regular fridge magnets seem to have infinite energy since they can continuously resist the force of gravity and so continuously exert a net force. How does this work?

Everything has gravity. Literally! EVERYTHING! Take an apple, yes. That has gravity and it's pulling your towards it but you're way too strong to avoid it. It's like the moon in the and the sun. The moon makes sure the Earth doesn't wonder off in space and the sun keeps us moving in the annual revolving path we take. So that's your answer about gravity.
Electric field is created by an electrostatic charge present in the universe. It is a conservative force and the electric field lines goes out of the positive charge and end at negative charge while a magnetic field is created by current that is moving charge. It is a non conservative force and the field lines are continuous. Direction of field lines are seen by thumb rule which says that on putting thumb in the direction of current and then curling the fingers shows the direction of magnetic field lines.
