What determines the direction of the magnetic force on a moving charge?

The right hand grip rule. You point the thumb on your right hand in the direction of the electric current and curl your fingers. The direction of your fingers gives the direction of the lines of flux.
It is undetermined what actually causes the induced charge to always be in this direction but it is probably a function of the electrons spin.

∙ 12y agoAn electric field lies perpendicular to the surface of a conductor. Its 'direction' is that of an isolated, positive, pole that is free to move within the field -i.e. from positive to negative.

∙ 14y agoThe direction of force on the charge determines the direction of current.
Positive charges are attracted to a negative voltage and negative charges are attracted to positive voltages.

∙ 13y agoThe direction of the force is determined by the sign of the chargee, and the angle between the direction of the moving charge V and the direction of the magnetic field B.
Force F = eVB= e(-V.B + VxB) = eVB[-cos(VB), sin(VB)]. .
eVxB is perpendicuar to the plane defined by VxB and eV.B is in the direction of the B field. The direction of the magnetic force is the resultant direction of B and VxB directions. If the angle between V and B is 90 degrees the direction is perpendicular to the palne defined by Band V. If the angle between B and V is an even multiple of 90 degrees the direction of the magnetic field is in the direction of B.

What is the effect of a magnetic field on a stationary electric field?
The magnetic field will have no effect on a stationary electric charge. ( this means that the magnetic field is also stationary. ) If the charge is moving , relative to the magnetic field then there might be an effect, but the size and direction of the effect will depend on the direction of the electric charge as it moves through the field. If the charge is moving parallel to the field there will be no effect on it. If the charge is moving at right angles to the field then it will experience a force that is mutually orthogonal to the field and direction of the motion. You really need diagrams to properly explain this
Does a magnetic field exert any pressure on a charge moving perpendicular to its direction?
Only moving charges experience force in a magnetic field. i.e.,on moving ,a charge q,with velocity v ,experiences a force in the presence of electric field(E) and magnetic field (B). It can be represented as F= q(v x B)~(Ftotal=Felectricfield + Fmagneticfield ) Force acts perpendicular to both magnetic field and velocity of the electron. Its direction is given by right hand thumb rule or screw rule. The magnetic force is zero if charge is not moving, since lvl=0.
A magnetic field does not interact with a?
A) stationary electric charge B) moving electric charge C) stationary magnet D) a moving magnet
Does a moving magnetic field produce an electric current?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
Why can a moving electron be deflected by magnetics fields?
A moving charge (or an electron) has a magnetic field around it. When it is moved in an external magnetic field in such a way that its direction of motion is not parallel to applied magnetic field. then both the fields interact to produce a FORCE on electron.Or you may say that A moving charge, when placed in a magnetic field , experiences a force given by:F=q(V*B) .In this equation, a CROSS PRODUCT is present between velocity "V" and magnetic strength "B" , SO direction of resultant force is at right angle to both V and B. hence force acts at angle of 90 degrees to displacement and hence does no work to change its speed.

Both gravitational and electrical forces act along the direction of the force fields How is the direction of the magnetic force ona moving charge?

Can a moving electric charge create a magnetic field?
Yes. A spinning charge will create a magnetic field as will a moving charge.
What are two fields surround a moving electric charge?
A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.
The force on an electron moving in a magnetic field will be the largest when its direction is?
perpendicular to the magnetic field direction
What effect does a magnetic field have on a charged particle?
Yes, a moving electron will create a magnetic field. Any moving charge will create a magnetic field around its path of travel. This is the basis for the electromagnetic force, which is one of the four fundamental forces in nature.
What is the field surrounding every moving electron?
An electron is surrounded by an electric field. The electron is negatively charged. A moving electric charge creates a magnetic field. Use the "right-hand rule". Point your thumb up and curl your finger a bit so your hand looks like it is holding a bottle. If the electric charge (e.g. electron) is moving in the direction of your thumb, then the magnetic field it creates moves counter-clockwise in the direction of your fingers.
The electric field passes through electrons.do the magnetic field have some sort of element like electron to exist?
Not that we are aware of. Magnetic fields are created by moving charge (electrons). The field is always at a 90° angle to the direction of the charge's motion. So an electron spinning around the nucleus will cause a tiny magnetic dipole, direction depending on which direction it is spinning. Atoms with multiple electrons may have electrons spinning in different directions which could cancel out the net effect, but if there is a net in one direction, and several those line up pointing in the same direction, then you have a magnet.
Every moving charge can produce a field?
magnetic field
What determines the change in direction of an object after it collides with another moving object?
the force or other moving object
Does Magnetic forces act when electrons move?
Yes. To be more accurate, a magnetic field is caused whenever there are moving electrical charges. Even the magnetic field in a permanent magnet are caused by more electrons moving around their atoms in one direction, than in the other.Yes.
