What do fast electrons that move through magnetic fields produce?

They produce forces: F=evB = e(-v.B + vxB) = e(-vBcos(angle) + vBsin(angle)).
The forces are quaternion conssiting of scalar force -ev.B and vector force evxB.
These forces create a orbit of motion in the magnetic field. If the angle is 90 degrees the force is a circle perpendicular to the magnetic field.

Would electromagnetic waves exist if changing magnetic fields could produce electric fields but chaning electric fields could not in turn produce magnetic fields?
no
What are two ways to produce electric fields electric fields are produced by charged particles or by changing magnetic fields?
One way to produce an electric field is through the presence of charged particles. When charged particles, such as electrons or protons, are stationary or in motion, they generate an electric field around them. Another way to produce an electric field is through changing magnetic fields. According to Faraday's law of electromagnetic induction, a changing magnetic field induces an electric field, causing the flow of electric charges.
Which diagnostic machines uses magnetic fields and radio waves to produce images of the brain?
magnetic resonance imaging, MRI
What brain imaging method uses radio waves and magnetic fields to produce a detailed image?
Electro-Magnetic imaging
How are magnets and motors related?
They both produce magnetic fields. So when together they attract.

What part of an atom is responsible for producing magnetic fields?
electrons
Can all currents produce magnetic fields?
yes
Do magnetic fields generate electric currents?
Not exactly. A CHANGING magnetic field, or a material moving through a magnetic field, will produce a VOLTAGE. This may or may not result in an actual current.
What do magnets have to with electricity?
Faraday showed that a wire passing through a magnetic field will produce electricity. This is how a generator works. Many windings of wire on an armature spin in a magnetic field. This makes electricity.
How torque is developed due to alignment of two fields?
Torque is developed by, among other things as well, the magnetic attraction or repulsion of two magnetic fields, contributing through rotational leverage to produce a net torque.
How does magnets produce movement ina current carrying wire?
Faraday's Law states that magnetic fields produce a electric fields and vice versa. Also, Ampere's Law states that a change in magnetic fields w.r.t. time creates current.
Do paired electrons create magnetic fields?
No - magnetism is created by moving electric charges.
What is the relationship between earths magnetic fields and the northern and southern lights?
because of electrons
Does electricity always produce a magnetic force?
Magnetism, an aspect of electromagnetism, one of the fundamental forces of nature. Objects such as a bar magnet can influence other magnetic materials, without physically connecting them, because magnetic objects produce a magnetic field. Magnetic fields are usually represented by magnetic flux lines. Magnetic fields influence magnetic materials and also influence charged particles that move through the magnetic field.
What depends on electric current to produce a magnetic field?
Your question is not quite crystal clear. However, a magnetic field is produced by a moving electric charge. Ordinarily, a current passing through a conductor will produce a magnetic field. In a fixed magnet, a group of the electrons has been organized so that their spins are aligned and this produces a permanent magnet. The Earth's magnetic field is the net result of a number of individual fields caused by electric currents generated in the hot interior of the mantle.
