Whenever electricity flows through a wire, it creates a magnetic field. In a single wire, this field is usually pretty weak. A coil, however concentrates the magnetic field. Each coil of wire contributes a small magnetic field and, together, they add up to make a much more powerful magnet...

But it is generally accepted that these ferromagnetic elements have large magnetic moments due to un-paired electrons in their outer orbitals. This is like having current flowing in a coil of wire, creating a magnetic field. Even the spin of the electron is thought to create a minute magnetic...
How to Make a Magnetic Force Field Change Detector: This is a very sensitive DIY magnetic force field change detector/sensor. Using HMC5883L magnetometer module with arduino nano. It also makes sound signals when the magnetic force field changes around t
The strength of a magnet in an MRI system is rated using a unit of measure known as a tesla. Another unit of measure commonly used with magnets is the gauss (1 tesla = 10,000 gauss). The magnets in use today in MRI systems create a magnetic field of 1.5-tesla to 7.0-tesla, or ...
All magnetic fields are created by moving charged particles. Stationary charged particles do not generate magnetic fields. An electromagnet is a magnet that relies on an electric current to produce the magnetic field. The simplest electromagnet is simply a wire carrying a current, which generates a...
