Contact UsDC electromagnet strength: voltage or current?
Big but. If you increase the voltage/current, you will increase the power dissipated by the magnet. And if you double the voltage you will increase power by a factor of 4. Since the magnet has lots of turns stacked on each other the interior of the magnet can get hotter than the outside, and you can wind up cooking the insulation.
Contact UsWhat happens when you increase current to a DC motor?
The drop depends on the type of battery and the current. If the current is above what battery is expected to provide, you can expect the battery to have lower voltage than expected, to overheat, maybe even explode. If the current provided by the battery is sufficient, the voltage drop isn''t going to be as big.

$begingroup$ I would advise NOT shorting any battery, even a small 9v battery of a few cubic cm in size can pack a s/c current of many amps and with thin wire you can burn your flesh (been there done that) if doing it with your fingers. A correctly sleceted resistor for value and wattage is better. e.g. for a small 9V battery a 27R resistor gives you 333mA and 3 Watts. $endgroup$
