What is the force of attaraction between two objects in a vacuum?
The force will always be gravitational. In addition we might have magnetic force, and electric force.?Regards.
Moving electric charges will interact with?
Moving electric charges will interact with an electric field. Moving electric charges will also interact with a magnetic field.
Do electric and magnetic fields always form closed loops?
Magnetic fields do, because there's no such thing as an isolated magnetic "pole", and a magnetic line always starts and ends at opposite poles of the same magnetized object. But electric fields don't. You can easily have a bundle of isolated positive charge over here and a bundle of isolated negative charge over there, whereupon the lines of the electric field start on one bundle and end on the other bundle. But electric field lines can also exist in closed loops, and they do that in radio waves, where the electromagnetic field propagates with an electric field component and a magnetic field component, and they both form closed loops.
What is the different electromagnets and permanent magnet?
Electromagnets are non permanent magnets. They got magnetic field because of applied electric field. They lost their magnetic field which was around that, when the applied electric field is stopped. permanent magnets have magnetic property always with it. Permanent magnetic property loses when we heat the material. It cannot be regained once again. But electromagnets are capable of regaining its magnetic properties.
When does electric current behave like a magnet?
An electric current is always surrounded by a magnetic field. This is more noticeable (for example, it can be detected with a compass) in the case of DC, and if the two wires of a circuit are separate.
What is the classical explanation of a dc electric current in a metallic wave?
A changing magnetic field always produces an electric field, and conversely, a changing electric field always produces a magnetic field. This interaction of electric and magnetic forces gives rise to a condition in space known as an electromagnetic field.

Is The electric part of the electromagnetic wave always 90 degrees from the magnetic part?
yes, always.
Is an electromagnet always magnetic?
No. Only when an electric charge is put through the electromagnet.
Can an electric current produce a field magnetism around it?
yes. electric current low always generates a magnetic field.
Can a electric current runnng along a wire be used to produce a magnetic force?
Whether or not you use it, there's always a magnetic field surrounding an electric current.When anything that can respond to a magnetic force is brought close enough to the current,it does feel a magnetic force.
Are electric currents magnetic?
A magnetic field is always associated with a moving charge. So, if current is there, it must be showing the magnetic effects though these are too small of daily relevance..
Moving electric charges will interact with?
Moving electric charges will interact with an electric field. Moving electric charges will also interact with a magnetic field.
How are magnet fields and electric fields alike?
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.
Do electric and magnetic fields always form closed loops?

But electric fields don't.

How do the electric and magnetic field of an electromagnetic wave regenerate each other?
No. Current flow creates electromagnetic fields in space. Electromagnetic fields, in turn, can create current flow in conductors. The electric fields do not directly create magnetic fields, nor do magnetic fields directly create electric fields.

Electromagnets are non permanent magnets. They got magnetic field because of applied electric field. They lost their magnetic field which was around that, when the applied electric field is stopped. permanent magnets have magnetic property always with it.
