The car charger is either 2amp or 4 amp for slow charge 10amp for fast charge and jump start Does it matter?
There's 2amp, 4 amp, and 10amp charger. Which charger to go with for powering an electromagnet of 208-230V and 50/60Hz ? What about 5 magnets in a series? Does it matter?

This is a bad idea. An electromagnet is designed to have an ac source or a very short interval of a dc source run through it. They generally have very low (.1 - 1 ohm) resistance and high reactances. This means that if a dc source is left the current will experience only the small resistance. Also the car charger is designed to be hooked to a car battery which has a very high internal impedance so it will probably just blow a fuse but it could cause a fire.

First, the charger puts out about 14V DC. Your magnets are rated for 208-230V AC. You would need an inverter to convert the DC current to AC. At 10 amps the charger supplies 140 watts. That is about 0.6 amps at 220V. Connecting 5 magnets in series will reduce the current flow by a factor of 5. At 0.1 amps, I doubt the magnets would pick up much. You would be better of buying a proper power supply.

If the electromagnet will settle for 12 - 14 volt DC, the charger could desire to artwork. in case you connect 5 magnets in series, the comparable cutting-edge will stay by using each. you probably did not grant adequate records with regard to the electromagnets to be certain if the magnetic rigidity may be the comparable or distinctive.
