What are the three forces responsible for a neodymium magnet to fall slowly down through a heavy copper tube?
Simon Bridge said:Welcome to PF;
That's a good question - what have you come up with so far?
i.e. have you listed the forces that are available to the universe? There are only four - but I feel the question may be treating one of them as two.

its a good experiment, as Simon has said, have a think about what is happening
A hint ... a moving magnetic field and a conductor
also it could be any magnet and it works just as well with an aluminium tube
I use this action to produce dampening in a seismometer ( earthquake detector)
but rather than an aluminium tube, I use a moving strip of aluminium between 2 fixed magnets

Electromagnetic radiation is a form of energy that is transmitted through space in the form of waves. It includes visible light, radio waves, microwaves, and X-rays.
Electromagnetic radiation travels through space at the speed of light in a straight line. It does not require a medium to travel, which is why it can travel through a vacuum.
Electromagnetic radiation is produced when an electric charge is accelerated or decelerated. This can occur naturally, such as in the case of lightning, or artificially, such as in the case of radio waves produced by a radio transmitter.
Electromagnetic radiation has a wide range of uses in various fields such as communication, medicine, and technology. It is used in radio and television broadcasting, medical imaging, and telecommunications, among others.
The electromagnetic spectrum is a range of all types of electromagnetic radiation, arranged in order of increasing frequency and decreasing wavelength. It includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Each type of radiation has different properties and uses.
