An electromagnetic field (also EM field) is a classical (i.e. non-quantum) field produced by accelerating electric charges. … The force created by the electric field is much stronger than the force created by the magnetic field.
Which one is stronger electric force or magnetic force?
An electric force is a force of attraction or repulsion between charged particles, which have unequal numbers of protons and electrons. … The higher the magnitude and the closer together two objects are, the stronger the electric force between them. A magnetic force is a force of attraction between magnetized materials.
Is electric field and magnetic field the same?
They are two different fields with nearly the same characteristics. Therefore, they are inter-related in a field called the electromagnetic field. … Without the electric field, the magnetic field exists in permanent magnets and electric fields exist in the form of static electricity, in absence of the magnetic field.
Why is a magnetic field stronger?
The magnetic field magnitude is proportional to the density of the lines. The closer together the field lines, the stronger the magnetic field. The more spread out they are, the weaker the magnetic field.
Is the magnetic field strong or weak?
The strength of the field at the Earth’s surface ranges from less than 30 microteslas (0.3 gauss) in an area including most of South America and South Africa to over 60 microteslas (0.6 gauss) around the magnetic poles in northern Canada and south of Australia, and in part of Siberia.
How strong is electric force?
The electric force between these electrons is 2.40 x 1043 times bigger than the gravitational force. In other words, electricity is almost a trillion-trillion-trillion-trillion-trillion times stronger than gravity.
Are electric and magnetic forces attractive or repulsive?
Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.
Can electric field exist without magnetic field?
Electric fields can exist without a magnetic field – consider a stationary point charge. Magnetic fields cannot exist without any E field component because there are no magnetic monopoles.
What causes magnetic fields?
Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. Each atom has electrons, particles that carry electric charges. … Their movement generates an electric current and causes each electron to act like a microscopic magnet.
How can you tell where the magnetic field is strongest?
The magnetic field is strongest at the poles, where the field lines are most concentrated. Field lines also show what happens to the magnetic fields of two magnets during attraction or repulsion.
