LIGO and Virgo make first detection of gravitational waves produced by colliding neutron stars
LIGO and Virgo make first detection of gravitational waves produced by colliding neutron stars For the first time, scientists have directly detected gravitational waves — ripples in space-time — in addition to light from the [...]
How to Make Magnetic Slime
How to Make Magnetic Slime Put a twist on the classic slime science project by making magnetic slime. This is slime that reacts to a strong magnetic field, like a ferrofluid, but it's easier to [...]
How to Make Liquid Magnets
How to Make Liquid Magnets A liquid magnet, or ferrofluid, is a colloidal mixture of magnetic particles (~10 nm in diameter) in a liquid carrier. When no external magnetic field is present, the fluid is [...]
The Science of Magnetic Field Lines
The Science of Magnetic Field Lines A magnetic field surrounds any electric charge in motion. The magnetic field is continuous and invisible, but its strength and orientation may be represented by magnetic field lines. Ideally, [...]
Magnetizing Steel without Special Tools
Magnetizing Steel without Special Tools Step 1 Find north. Find north. If you have a compass, the needle will point directly to magnetic north. Otherwise finding true north should be good enough for this method. [...]
Magnetize Steel Using a Battery
Magnetize Steel Using a Battery Strip the insulation off both ends of a wire. Using wire stripping pliers, strip about 1 in (2.5 cm) of insulation from each end of an insulated wire. You'll need [...]
Magnetizing Steel Using an Existing Magnet
Magnetizing Steel Using an Existing Magnet Use this to quickly make a temporary magnet. Keep a strong magnet around, and you can magnetize some types of steel with a couple minutes of work. This turns [...]
Making an Electromagnet
Making an Electromagnet Gather the necessary materials. To make an electromagnet, you will need insulated copper wire, a piece of metal with known iron content, a 12-volt battery (or other DC power supply), wire strippers/cutters, [...]
