Let's assume that there is an electromagnet with $B=1T$, what is the magnitude of the force it could generate on other dipoles equal to it's surface area? Can the magnitude of force (in newtons) be determined from $B$?

You can still ask an expert for help

The shape of the field is important for attracting force. Dipole field force varies as the inverse cube of the distance. Beyond that, a sharp edge or a point will have huge field divergence. Magnetically permeable bodies will be sucked in, riding the divergence. Note the pole pattern in refrigerator magnets and channel magnets. For a given total field, one can be clever with addition and subtraction re Halbach arrays.

"The only power consumed in a DC electromagnet is due to the resistance of the windings, and is dissipated as heat."

Is this true? So powerful magnets like junkyard magnets don't consume electricity apart from resistance?

How much does electricity does a junkyard or any other powerful super magnet consume?

(a) A car generator turns at 400 rpm when the engine is idling. Its 300-turn, 5.00 by 8.00 cm rectangular coil rotates in an adjustable magnetic field so that it can produce sufficient voltage even at low rpms. What is the field strength needed to produce a 24.0 V peak emf? (b) Discuss how this required field strength compares to those available in permanent and electromagnets.

There is a close relationship between magnetic torces and the generation of electricity. Explain how magnets can be used to generate electricity and how electric current can be used to create electromagnets. For each process, give an example of a device you would find around the home.

Light can be slowed down to a walking pace and even stopped in a medium of hot rubidium vapour. If an electromagnet was placed in this medium and turned on would the popagation of the magnetic field be slowed down or stopped?
