How is this possible?

[jpqtuts]

You can explain it with physics. Ask Eddy if you want to know more

[knightdb]

Eddy currents creating magnetic fields

[go_beyond_the_sky]

Simple 'eddy current' phenomenon.

[akashverma]

Critically damped oscillation under eddy current effect.

[plancksConstantt]

Faraday and Eddy can give you the best explanation to it

Sir what is the basic requirements in order to start with your 8.03 lectures and from where i can understand that ....
As i am preparing for neet exam

[Jamesbondhere]

Sir please correct me if I explained it wrong. I suppose the slab is a magnet/electromagnet and the ball is a conductor as it's wrapped with aluminium foil. There is a change in magnetic flux as the ball moves, which induces currents on portions of the foil called Eddy currents. These currents produce heat, hence the ball slows down due to loss in it's kinetic energy which is completely converted to heat.

[frankycubalibre]

Almost critically damping....Eddy currents acting.

[SURENDERKUMAR-kdoo]

This ball is a magnet and under marble there is copper which stop the magnet ball😅

[I___]

aluminum plate and magnet in a ball)))

[rakshitkakar]

Electrostatic force ?? The ball and plate might be oppositely charged that's why the ball got a retardation force

[mohamadalimokadem]

This is one of the 8.02 lectures where professor Lewin explains this phenomenon if you're interested in a detailed explanation

[largeformatprinter]

Magnetic breaking. The moving magnet creates opposing Eddie currents in the aluminum plate
