Magnetism; the path of electrons

In summary, the path of electrons from an accelerator must be bent by a 90° angle to avoid hitting a barrier a distance d away. To accomplish this, a 'bending magnet' with a uniform field B that extends over an area d*d is used. The minimum magnitude of B is B >= sq rt (2*m*K/e²d²), where m is the mass of a proton and K is its kinetic energy. The magnet is able to turn charged particles by applying a force on them through its magnetic field.

The path of electrons emerging grom an accelerator must be bent by 90° by a 'bending magnet' so as not to strike a barrier in their path a distance d from their exit hole in the accelerator.
Show that the field B in de bending magnet, which we assume is uniform and can extend over an area d*d, must have magnitude B >= sq rt (2*m*K/e²d²), with m the mass of a proton and K is its kinetic energy.

How can I solve this porblem?
I really don't see it...

Welcome to PF;
You know that magnets can turn charged particles?
How do they do this?
 

Related to Magnetism; the path of electrons

1. What is magnetism?

Magnetism is a fundamental force of nature that describes the interactions between magnetic materials. It is the ability of certain materials, like iron, nickel, and cobalt, to attract or repel other materials.

2. What is the path of electrons in magnetism?

In magnetism, electrons follow a curved path around the magnetic field lines. This is due to the force exerted on them by the magnetic field, which causes them to move in a circular motion.

3. How are magnetism and electricity related?

Magnetism and electricity are closely related as they are both manifestations of the same fundamental force, known as the electromagnetic force. This means that any electric current will create a magnetic field, and a changing magnetic field will induce an electric current.

4. Why do electrons move in a specific path around a magnet?

The movement of electrons around a magnet is due to the alignment of their magnetic moments with the external magnetic field. This causes them to experience a force that makes them move in a circular path.

5. How does magnetism affect matter?

Magnetism can affect matter in various ways, such as attracting or repelling other magnets, aligning the magnetic moments of atoms, and inducing electric currents. It also plays a crucial role in the formation and behavior of materials, such as ferromagnetic materials, which have strong magnetic properties.
