Resultant magnetic force

What is resultant magnetic force? can you please explain with an example. (Shreya) Answer: When a magnetic substance (or a magnet) is placed in a region where there are multiple magnetic fields, the net force due to all of them is called the resultant. In other words, it is that magnetic force which can effectively […]
