it only depends on your magnet.
A charged particle must be moving in a magnetic field in order to experience a magnetic force. If the particle is stationary, it will not experience a magnetic force.
It must be moving
not always as the south pole of a magnet is magnetic yet it repels another south pole. :D
Because it's not necessary for objects to be in contact (touching) in order to feel the magnetic force between them.
An object must be made of a ferromagnetic material, such as iron, nickel, or cobalt, in order to be magnetic. These materials have unpaired electrons that align in the presence of a magnetic field, creating a magnetic force.
A transformer relies on an alternating current in order to work. An electrical transformer converts electromotive force to magnetomotive back to electromotive. In order for an electromotive force to be induced by a magnetic field, the field must be moving.
True. According to Faraday's law of electromagnetic induction, a changing magnetic field can induce an electromotive force (emf) in a conductor, resulting in the generation of an electric current.
No, two objects do not necessarily have to touch in order for a force to act between them. Forces such as gravitational, magnetic, and electric forces can act over a distance without requiring physical contact between the objects.
Selenium is diamagnetic; it only creates a magnetic field in opposition to an external magnetic field.
An object must experience a net force in order to accelerate. This force causes the object to change its speed, direction, or both, resulting in acceleration. The magnitude of the acceleration is directly proportional to the force applied on the object.
The first place i'd look would be on Ebay or Craigslist. If you can find anything there I would recommend looking into company's that deal in the steel and magnetics.
After several shakes, the iron filings lose their organized alignment with the magnetic field of the magnet. Initially, they align along the magnetic lines of force, demonstrating their magnetism. However, the shaking disrupts this order, causing the filings to scatter and lose their magnetic orientation. As a result, they may no longer visibly demonstrate magnetism unless re-aligned by the magnetic field.
