Why is a small bar magnet able to deflect a compass from Earth's large magnetic field?
The small bar magnet has a stronger magnetic field, at least at short distances.
Does plastic constrain a magnetic field?
Not really. Plastics are almost all hydrocarbons, and the magnetic field lines go right through plastics like the plastics were invisible. That's the short answer, but it contains the essentials.
Where is a bar magnet's pull strongest?
A bar magnet is strongest at its ends, or poles. This is because there is a magnetic field, or B field, that is produced by the magnet itself. The magnetic field can be represented by magnetic field lines, which enter one end of the magnet and exit the other.For instance, in a bar magnet, the magnetic field lines emerge from the north pole of the magnet and enter the magnet at the south pole. Since a magnet has two poles, it is said to be a magnetic dipole.The magnetic field lines are most closely packed together at the poles, since it is a short distance to the opposite pole of the magnet. This is why a bar magnet is most effective at short distances. Picking up a paperclip from a centimeter or two away is much easier than trying to magnetically attract a paperclip to a magnet from a distance greater than five or six centimeters.
Why can you feel an attractive force several centimeters away from the surface of the fridge?
The attractive force you feel several centimeters away from the surface of the fridge is due to the magnetic field generated by the magnets used in the fridge's door seal. These magnetic fields can extend beyond the immediate surface, allowing them to exert a force on ferromagnetic materials nearby. Additionally, the magnetic field strength decreases with distance, but it can still be strong enough at a short range to feel the attraction. This phenomenon is a result of the fundamental properties of magnets and their interaction with magnetic materials.
Why would a compass needle move when placed near a circuit?
Any time current flows through a conductor an electromagnetic field is formed around the length of that conductor. The direction of current flow determines the polarity of this magnetic field.

Can a magnetic Field short out appliances?
No, a magnetic field alone cannot short out appliances. However, if a strong magnetic field causes a magnetically induced current to flow in the appliance's circuits, it could potentially damage the appliance.

What is the effect of the magnetic field of a short wire on nearby objects?
The magnetic field of a short wire can attract or repel nearby objects that are sensitive to magnetic forces. This effect is stronger the closer the objects are to the wire and can cause them to move or align in a certain direction.
What uses short bursts of a magnetic field to produce images?
the magnetic resonance imaging, also abbrieviated as: M.R.IA digital camera uses short bursts of a magnetic field to produce images. The images are then stored on a disk or other memory source within the camera. The disk can then be inserted into most computers to download the images.
