Several folks are daunted by the thought of fixing electrical issues at home and their initial instinct is to call a professional. Although this is the finest program of action, there are a handful of ‘do it yourself’ jobs out there for the much more adventurous house handymen. Getting some fundamental electrical tools will make the entire world of a distinction. Here are a number of should haves.
Circuit tester: A circuit tester is employed to test the presence of electricity. It plugs into an electrical outlet and tells whether or not the circuit is "hot" or correctly grounded.
Neon voltage tester: A neon voltage tester is an additional modest but really useful electrical device employed to know regardless of whether wires are "hot" or not.
Continuity tester: A continuity tester is a small battery-operated electrical tool used to determine regardless of whether wiring is damaged and electrical circuits are total or not.
Wire Crimper: A wire crimper is use to strip wires and to crimp lugs onto the wire.
Screwdrivers: A screwdriver is employed to tighten or unscrew screws and everyone ought to have at least 1 in this family. It would be finest to individual a screwdriver kit with all sorts of screwdrivers. Both Phillips-head (+) and Flat-Bladed or Slotted ( - ) screwdrivers are important. Be confident that they have an insulated rubber grip as nicely.
Wire Stripper: A wire stripper strips or removed the cover from the conductor or a wire. Most electrical wires employed in property electrical wiring have a plastic or rubber insulation. These insulations or covers require to be eliminated when you splice the wires or connect them to gadgets. A great wire stripper serves this objective. Although doing work with a wire stripper, it is important to use the proper wire gauge.
Lengthy-nose pliers: Long-nose pliers are employed for bending modest loops at wire ends and for cutting off wires. A extended nose plies is quite helpful to hole wires at spots exactly where normal pliers or finger don't reach.
Lineman's pliers: A pair of lineman’s pliers is the best device for cutting hefty wire or cable and twisting wire ends with each other.
Allen Wrench Set (Hex Set): Allen wrenches are utilised to tighten allen-headed screws in an electrical panel.
Multi-meter:
A multi-meter is employed in most electrical operates. It is utilised to test - continuity, voltage, output voltage and so forth.

What can I do to make my electromagnet stronger?
I am using 14 gauge insulated wire and 2 six-volt batteries. the wire makes 16 turns around a 4-inch long bolt. It's not producing nearly the amount of magnetism I need. Does anyone know how I can make it stronger?
By the way, I'm using this to make an induction coil, and according to my science project page, I want to have many times more turns in the secondary coil than the primary, just wondering if that's true.
There are a couple of things you can do. The easiest things are to increase the number of turns on the bolt. The more turns the stronger the magnet.
Also, the more current through the wire the stronger the magnet. Every battery has some internal resistance that limits the amount of current it can provide. Connecting the batteries in parallel effectively cuts this series resistance in half, allowing more current to be delivered to the electromagnet. Try that.. Adding more batteries also works..
So, you could do this by using more batteries. Also, try connecting the batteries in parallel instead of in series. Be careful though. As you add more power, the windings will get hot enough to cause burns if you touch them.
But, stick with batteries, they're safe.. Don't be tempted to do what i did when I tried this as a kid and put an electrical plug on the end of the winding and plug it into a wall socket (the more power the better, right? lol) If you survive, you'll have a blown circut breaker, a smoked filled room, burned fingers and a lot of explaining to do.. (I know this from first hand experience, since I survived, lol)
Instead of a straight bolt, one thing you can try is to use a U-bolt. Bend the ends of the U-bolt together so that they are almost, but not quite touching. Then, put as many windings as you can around the bolt. Because the ends of the U-bolt are so close, you will develop a strong magnetic field between them. When you have a straight bolt or nail, you're only working with the magnetic field at one end.
One thing you can do is to run some experiments to see what helps and what doesn't. For example, count the number of paper clips the magnet can pick up. Then change the number of windings and do it again. Plot a few points and you'll get a sense of the relationship between the strength of the magnet and the number of windings required. Could do a similar experiment using different numbers of batteries. If you use two batteries instead of one, can you pick up twice as many paper clips? How about three batteries, etc..
Hope this helps,
