Is there any other way of testing whether or not you have a 1944 Steel penny that won't damage the penny. The magnet test doesn't seem to work cause even when I try to get a 2007 penny to stick to the magnet...it won't. So is there some kind of magnet needed? Like power wise or anything like that, if not then I need to know what are other ways of testing the 1944 penny.

Weigh it.
I'm not an expert on coins, but if the 1944 was 100% steel, I would expect it to weigh something different then modern pennies.
Another test would be to measure the resistance with a micro-ohm meter. This is a specialized device that can measure resistance to a millionth of an ohm. Steel should have a different resistance than the metals used on other pennies.
Here are some comments from wikipedia:
In 1943, at the peak of World War II, cents of zinc-coated steel were made for a short time due to war demands for copper. A few (the U.S. Mint reports forty) copper cents from 1943 were produced from the 1942 planchets remaining in the bins. Similarly, some 1944 steel cents have been reported. Following 1943, salvaged ammunition shells made their way into the minting process, and it was not uncommon to see coins featuring streaks of brass or having a considerably darker finish than other issues.

You probably have an imitation. There are only a few known 1944 steel pennies in existence. Most of them are plain old copper cents that have been zinc coated to look like steel. If yours sticks to a magnet, it might really be steel. Check it under a strong magnifying glass to make sure it's not a plain old ordinary 1943 steel penny where someone's altered the date.

are you using a real magnet or a fridge magnet? (fridge wont work because its not strong enough[ive tried on mine dont know bout yours]) the magnet test is the best way to find out if it is steel or not. your 2007 doesnt stick because its copper and copper's magnetism is relatively low thus it doesnt stick, also some pennies are magnetic due to the percentage of other alloys in it, check on wikipedia on your coin it has some more descriptions about that '43/'44 year's penny. hopefully this helps.

To be magnetic, a coin must have a material in it's alloy that is itself magnetic, i.e. steel or nickel. The degree of magnetism will, of course vary with the amount of magnetic material in it.
