For a project, I am creating an electromagnet. It works to my liking on a 12-volt lantern battery that has 7500mAh. I was wondering if I could instead use an AC to DC adaptor with the round end of it cut off and the split wires going to the positive and negative of my electromagnet. If the adaptor output is similar in voltage/amps to the battery, is the DC electricity leaving the adapter just as safe as the battery, or are their other considerations that I am not taking into account that would make this electricity less safe than battery electricity?

At that voltage, neither is dangerous, that due to the fact your body has an high resistance R.
A DC adaptor doesnt supply the same kind of steady voltage as a Battery. Those things are somewhat of a step type of output. They contain only a single wave rectifier. You would need a Wheatstone Bridge and capacator circuit to better duplicate the DC battery's output. You might consider getting or building yourself a Scope to view these things as it is very educational. Everyone your age builds a Heath Kit Scope, Its traditional Get a kit off the Net .

Take a cup of water and pour a great number of salt into it. Then carry 2 hands of the comparable hand into the salt water. touch the two poles of a 9V battery and you gets a ask your self. The ask your self must be very susceptible or somewhat painful counting on your pores and skin and for the way long your hands have been soaked interior the salt water. yet regardless of dry palms you will get a ask your self from low voltage DC if e.g. you have an harm and are bleeding. electrical energy flows unquestionably by way of blood. in no way enable the present run from one hand to the different.
