Homework Statement
Show that B = (k)v(cross)E
The Attempt at a Solution
I have no idea where to start. I have the F = qE and F = q(v(cross)B)
Tareth said:Just a starting point would be much help.
Tareth said:That is the first part of the problem.
Show that [tex]\vec{B} = k\vec{v}\times\vec{E}[/tex]
The relationship between electric and magnetic fields is known as electromagnetism. This means that an electric field can create a magnetic field, and a changing magnetic field can induce an electric field. This is described by Maxwell's equations.
Electric fields are created by charges, such as electrons or protons. Magnetic fields are created by moving charges, such as an electric current. These fields are also created by changing electric and magnetic fields, as described by Maxwell's equations.
No, electric and magnetic fields are always interconnected. A changing electric field will always produce a magnetic field, and vice versa. This relationship is known as the electromagnetism and is fundamental to understanding many phenomena in physics.
The main difference between electric and magnetic fields is their orientation. Electric fields are created by charges and point away from positive charges and towards negative charges. Magnetic fields, on the other hand, are created by moving charges and are always perpendicular to the direction of motion.
Electric and magnetic fields can be measured using specialized instruments such as voltmeters and magnetometers. These instruments can measure the strength and direction of the fields at a specific point. The units for electric fields are volts per meter (V/m) and for magnetic fields are teslas (T).
