What else can I help you with?
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 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.
What is the direction of force acting on a charge moving along the direction of magnetic field?
The force acting on a charge moving in the direction of a magnetic field is perpendicular to both the direction of the charge's movement and the magnetic field. This force is known as the magnetic Lorentz force and will cause the charge to move in a circular path.
How does an electron behave in a magnetic field?
If you wrap a coil of wire around a bar of iron and pass a current, an electromagnet will result. This principle is used in generators where the casing is magnetised and the rotor rotates in the magnetic field inside the casing(the armature), inducing a current in the rotor winding.
How does the direction in which current carrying wire is forced when in a magnetic field compare with the direction that moving charges are forced?
The direction in which a current-carrying wire is forced in a magnetic field is perpendicular to both the direction of the current and the magnetic field according to Fleming's left-hand rule. Moving charges are also forced in a direction perpendicular to both the direction of their motion and the magnetic field according to the Lorentz force equation.

What happens if the electron enters the magnetic field parallel to B?
If an electron enters a magnetic field parallel to the field lines (i.e., parallel to B), it will not experience any deflection or force due to the magnetic field. This is because the force on a charged particle moving parallel to a magnetic field is zero.

What is the direction of the force on an electron that is moving alongside a wire that is carrying a current in the opposite direction?
The force on the electron would be perpendicular to both the direction of its motion and the current flow in the wire. This is described by the right-hand rule for magnetic fields, where the force would point in a specific direction based on the orientations of the current and the electron's motion.
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.
What is the direction of force acting on a charge moving along the direction of magnetic field?
The force acting on a charge moving in the direction of a magnetic field is perpendicular to both the direction of the charge's movement and the magnetic field. This force is known as the magnetic Lorentz force and will cause the charge to move in a circular path.
What is the magnetic field due to the wire at the location of the electron?
The term "magnetic field" refers to the strength of magnetism surrounding electrical currents or magnetic matter. Electrons play a large part in the process of magnetism, as moving electrons will generate a magnetic field.
When cathode rays are passed through a magnetic field which pole do they deflect towards north or south and why?
Cathode rays are electron beams. When they are moving in a magnetic field, they are deviated. The direction of their deflection is given by Fleming's left hand rule. The direction of deflection, current (which is the reverse of the direction of the electron beams) and field are all perpendicular to each other. Hence, the electron beam will deviate in a direction contained in a plane which is perpendicular to both the field and the electron beam. Hence, the cathode rays are neither defleted to the north nor south pole.

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.

How does the direction in which current carrying wire is forced when in a magnetic field compare with the direction that moving charges are forced?
The direction in which a current-carrying wire is forced in a magnetic field is perpendicular to both the direction of the current and the magnetic field according to Fleming's left-hand rule. Moving charges are also forced in a direction perpendicular to both the direction of their motion and the magnetic field according to the Lorentz force equation.
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.
