Bar Magnet Magnetic Field
The strength of the magnetic field is proportional to the number of turns and magnitude of the current. The magnetic field produced by a solenoid is similar to a bar magnet.

When this material is exposed to an electric current the magnetic field is generated making the material behave like a magnet.
. Magnetic field lines are parallel inside the solenoid similar to a bar magnet which shows that the magnetic field is the same at all points inside the solenoid. And attracts or repels other magnets. Here is a short video showing and easy experiment performed with a neodymium cube magnets and some iron filings that will demonstrate the magnetic field produced by this product.
Soft magnetic materials can be magnetised by a relatively small magnetic field and when this is removed they revert to low residual magnetism. Magnetic Classification of Materials. The magnetic field can also be seen with a piece of Magnetic View Film Green 4x6.
Difference Between Electromagnet and Permanent Magnet. A permanent magnet is an object made from a material that is magnetized and. A force that pulls on other ferromagnetic materials such as iron steel nickel cobalt etc.
Earths magnetic field also known as the geomagnetic field is the magnetic field that extends from Earths interior out into space where it interacts with the solar wind a stream of charged particles emanating from the SunThe magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earths outer core. A magnet is a material or object that produces a magnetic fieldThis magnetic field is invisible but is responsible for the most notable property of a magnet. The strength of the magnetic field can be controlled by controlling the electric current.
Hard magnetic materials retain a large amount of residual magnetism after exposure to a magnetic field. Magnetic field lines of a Neodymium Magnet as illustrated below with the iron filings. Magnetic materials can be classified as Hard or Soft.
