Both act only on charged particles (ions, protons, or electrons). ?However, an electric field (which generates an ELECTRIC FORCE) acts on a particle in the same direction as the field, given by the equation:
F(vector) = q*E(vector)
The resulting force vector is in the same direction as the field vector (for positive charges).
A magnetic field generates a force ONLY on a MOVING charge, and ONLY if the charge is moving non-parallel to the magnetic field:
F(vector) = q*v(vector) x B(vector)
Because of the cross-product, the magnetic force is a direction perpendicular to the velocity and magnetic field vectors (use the right hand rule to figure out the direction of magnetic force). ?The particle will still have momentum from its initial velocity, so an applied magnetic field will (pretty much) always make the particle move in a curved path.

∙ 13y agoBoth the electric and magnetic forces act on charged particles. The electric force acts on any charged particles whereas the magnetic force acts on moving charged particles only. In addition, the magnetic force can only appear when an electrically charged particle is moving.

near the source, they decrease the longer distance from the source and they are
at right angles to each other. Check out the link.

∙ 9y agoMagnetic and electric fields are not really alike at all! Magnetic fields are set up by moving charges -so an electric current causes a magnetic field. Electric fields are set up by differences in potential, so an electric field will exist between two points at different potentials.
Magnetic fields surround a current, concentrically. Electric fields spread radially between objects at different potentials.

How are electromagnet and a bar magnet alike?
Both are magnetic.
Name two things that a magnet force can pass through?
what are the things pass through magnet fields?
The magnetic fields of any magnet are greatest to?
north pole
How can we increase the magnitude of the magnetic field of an electric magnet?
Increase the magnitude of the electric current.
What causes a magnet to loose its magnetism?
high temperature, AC magnetic fields, mechanical shocks, and physical distortion.
For a permanent magnet where is the energy associated to the magnetic field of the magnet stored?
For both the magnetic and electric (static) fields, energy is considered to be stored in the field.
What magnet is made by electric currents?
All electric currents create magnetic fields. If you wind wire into a coil and pass current through the wire, that is an electromagnet.
Is an electric bell a permanent magnet?
An electo-magnet is used in an electric bell.
How are electro magnet like bar magnets?
a bar magnet and a electromagnet are alike in many ways. the are alike because both of them are magnets. but there are plenty other ways they are alike
Can an electric field be compressed?
Electric fields are similar to magnetic fields, and can be "compressed" by the imposition of other electric or magnetic fields.
How are motors and magnets alike?
Magnets and electric motors are similar in that they both produce magnetic fields.
How are electromagnet and a bar magnet alike?
Both are magnetic.
What produces magnetic fields?
the presence of a magnet
How are moving electric charges related to electric and magnetic fields?
Moving electric charges create electromagnetic fields.
Can an electric current exert a force on a magnet?
In a conductor - only if the field is moving, thus changing.
What is a magnet that is creadted from electric current through a wire?
Electro-Magnet
Can you accelerate a stationary charged particle witha magnetic field or an electric field and please explain?
Yes.You must understand that magnetic fields induce electric fields 90 degrees out of phase (or perpendicular) to them, and vice versa.A charged particle will want to move one way or another when put within an electric / magnetic field, because the field will provide a push or pull on that particle in a specific direction.The easiest physical way to view this is with two magnets - imagine a small stationary magnet. If you take another magnet and hold it close to the stationary magnet, the second magnet will be creating a magnetic field that will either push the stationary magnet away or draw it closer. The same thing can be done by creating an electromagnet (push current through a coil of wire near the stationary magnet).
