Theoritically. I am using Biot - Savart's law to find the magnetic field in some point. But can someone say, how then I can find the force acting on my particle?

Hi! Thanks for the answer! Do you think that this force can be found using Biot-Savart's law? I mean, to use and then integrate over the whole coil.

I think that the magnetic field of finite coil isn't uniform. At all I am using a coil with small lenght (not like a solenoid). So the magnetic field won't be uniform. As I know the magnetic field inside infinitely long solenoid is uniform, but our case is not such.

Hi there, I am working on a research paper and I need to determine the force with which the magnetic field of a coil acts on an small (pink-pong sized) iron ball. I tried to search for the force, acting of three dimensional object in magnetic field, but the only force I found was: F = q0vB I...

Hi, there! I am studying magnetism right now and I can’t understand how does a magnet work. I read that the magnet has a magnet field, which influences only charged particles with velocity. But then how does magnet attracts metal objects, e.g iron nail? I read that in metals there are free...
