How do i connect 10 electromagnets to arduino nano?

May i use a card like these?

These are the electromagnets i have:

Which should be the voltage of the lipo battery, may i use this:

thank you

Your Arduino and your relays both require 5 VOLTS! Why do you think 12 volts from a battery is appropriate?

as far as i know arduino nano can run on 5 to 12 v
my electromagnets run on 6 v, sorry my mistake, i wanted to say 6v not 12v.

Is that relay appropriate?

Not from a 12 volt battery!

No.
The Arduino can be powered from 7V to 12V.or it can be powered from a 5V supply.
But the Arduino always runs at 5V.

The signals from it are 5V and the current must not be allowed to exceed 30mA or so, so you should never connect an Arduino output to anything that will draw more current.
