Motor magnet

[erbi]

Can somebody help me building a machine which increase the magnetic field of motor and can somebody tell what I need to have to measure the field ?

If you mean to remagnetize the magnets this can be very difficult, depending on the type of magnet and their size.

Magnetic field measurement is usually achieved using a gaussmeter (these have a Hall probe sensor):

If you need more magnetic field, you can switch to RareEarth magnets instead of Ferrites. They are 3-4 times stronger than Ferritte magnets. For samples, contact companies like Dexter Magnetics or Magnet Sales.

They have inexpensive handheld gaussmeter.
