Neither. You get a force in the direction perpendicular to both the field and the velocity of the electron. Look up the Lorentz force if you are familiar with cross products of vectors, or Fleming's Left Hand Rule if you aren't.gmoney909 said:does a magnetic field repel or attract electrons ?
Magnetic repulsion, usually.gmoney909 said:Also when you place two magnets together with the same polarity and you feel that pressure - what is this called
Sure. Changing magnetic fields is one way to steer an electron (or any other kind of charged particle) beam.gmoney909 said:can protons or electrons pass through this field
A magnetic field is a region in space where a magnetic force can be detected. It is created by moving electric charges or by magnetic materials such as magnets.
Magnetic fields can exert a force on objects that have magnetic properties, such as iron or steel. This force can cause the object to move or align with the direction of the magnetic field.
Magnetic fields can be measured using a device called a magnetometer, which detects the strength and direction of the field. There are also apps available for smartphones that can measure magnetic fields.
A magnetic field can be created by running an electric current through a wire or by using a permanent magnet. The shape and strength of the field can be manipulated by changing the orientation and distance of the magnet or wire.
Magnetic fields have a wide range of applications, including in electric motors, generators, MRI machines, and particle accelerators. They are also used in everyday objects such as credit cards, speakers, and compasses.
