magnetic field lines. 03
Answers
Explanation:
Magnetic field lines are defined to have the direction that small compass points when placed at a location .if small compasses are used to map the magnetic around a bar magnet, they will point in the directions shown : away from the north pole of magnet ,toward the South Pole of magnet.
Answer:
Magnetic fields, like gravitational fields, cannot be seen or touched. We can feel the pull of the Earth’s gravitational field on ourselves and the objects around us, but we do not experience magnetic fields in such a direct way. We know of the existence of magnetic fields by their effect on objects such as magnetized pieces of metal, naturally magnetic rocks such as lodestone, or temporary magnets such as copper coils that carry an electrical current. If we place a magnetized needle on a cork in a bucket of water, it will slowly align itself with the local magnetic field. Turning on the current in a copper wire can make a nearby compass needle jump. Observations like these led to the development of the concept of magnetic fields.
