1st question: How are magnetism and electricity related
The telegraph invented by Samuel F. B. Morse uses an electromagnet to make noise, certain sounds stand for different letters. A dot is a short sound a dash is a longer sound.
Morse code A=.-, B=-..., C=-.-.,
D=-.., E=., F=..-., G=--., H=...., I.., J=.---, K=-.-, L=.-.., M=--, N=-., O=---, P=.--., Q=--.-, R=.-., S=..., T=-, U=..-, V=...-, W=.--, X=--., Y=-.--, Z=--.

1st question: How are magnetism and electricity related
How the Telegraph worksWhen you push down the key it gives the electrons a free path which activates the electromagnet which pulls the strip down.
The strip makes a noise when it hits the nail.

1st question: How are magnetism and electricity related
I made a coil with 1,000 turns around a plastic tube and attached a light bulb to the wires. When you drop a magnet through the tube the light bulb lights up. This is a very simple generator.

Conclusions
Part A: An electric current has a magnetic field and if you coil it around a metal object it creates an electromagnet.
Part B: A moving magnet makes an electric current.
