Study the scenario.

A magnetic field is generated when using an electromagnet. The events that occur to create the magnetic field are listed below.

The magnetic domains align inside the piece of metal.

Close the circuit so a current flows through it.

Wrap a wire to create loops around a piece of metal, such as iron.

The magnetic field is generated inside the loops.

What is the correct order of events?

1. C, A, B, D

2. A, C, B, D

3. B, A, D, C

4. C, B, D, A

Aprisoner is forced to go into one of three rooms, but he can choose which room. the first room is ablaze with fire. the second one is rigged with explosives that will go off as soon as he enters. the third contains a pair of lions who haven't eaten in years. which room should he choose to survive?

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?

Electromagnetic force is present when electromagnetic fields a.become charged as they lose electrons. b.become stable as they come in contact with other forces. c. interact with charged particles. d.gain energy from other forces.
