What is the magnitude of force F on a charge q moving with a velocity v in a perpendicular magnetic field B?

What is the magnitude of force F on a charge q moving with a velocity v in a perpendicular magnetic field B?

F = qvB sinθ
The force is perpendicular to both the velocity v of the charge q and the magnetic field B. 2. The magnitude of the force is F = qvB sinθ where θ is the angle < 180 degrees between the velocity and the magnetic field.

What is Lorentz force write an expression for it when is a magnetic force maximum?

Lorentz force, the force exerted on a charged particle q moving with velocity v through an electric field E and magnetic field B. The entire electromagnetic force F on the charged particle is called the Lorentz force (after the Dutch physicist Hendrik A. Lorentz) and is given by F = qE + qv × B.

What is Q in F qvB?

The equation is given by F = q v × B or F = qvB sin θ, where q is the charge, B is the magnetic field, v is the velocity, and θ is the angle between the directions of the magnetic field and the velocity; thus, using the definition of the cross product, the definition for the magnetic field is.

What is Q in magnetic field?

If a charge q is moving with uniform velocity v parallel to the direction of a uniform magnetic field B, it experiences no force. Your thumb points in the direction of the vector product v × B. If q is positive then this is the direction of F. If q is negative, your thumb points opposite to the direction of F.

What is Q in physics magnetic field?

It says that the electromagnetic force on a charge q is a combination of a force in the direction of the electric field E proportional to the magnitude of the field and the quantity of charge, and a force at right angles to the magnetic field B and the velocity v of the charge, proportional to the magnitude of the …

What is the magnitude F of the magnetic force on the charge?

Magnitude of the Magnetic Force The magnetic force on a charged particle q moving in a magnetic field B with a velocity v (at angle θ to B) is F=qvBsin(θ) F = qvBsin ( θ ) .

What is the magnitude B of the magnetic field?

Equation : B=2πRμ0​i​ gives the magnitude B of the magnetic field set up by a current in an infinitely long straight wire, at a point P at perpendicular distance R from the wire. Suppose that point P is actually at perpendicular distance R from the midpoint of a wire with a finite length L.

What is magnetic force Q?

What is the B in F IlB?

For a wire exposed to a magnetic field,F=IlBsinθ F = IlB sin ⁡ describes the relationship between magnetic force (F), current (I), length of wire (l), magnetic field (B), and angle between field and wire (θ).

What force does a magnetic field exert on another moving charge?

Magnetic fields exert forces on other moving charge. The force a magnetic field exerts on a charge q moving with velocity v is called the magnetic Lorentz force . It is given by It also is perpendicular to the direction of the velocity v. ( Review the vector or cross product!)

What is the magnitude of magnetic force on a stationary charge?

The magnitude of the force is F = qvB sinθ where θ is the angle 180 degrees between the velocity and the magnetic field. This implies that the magnetic force on a stationary charge or a charge moving parallel to the magnetic field is zero.

Why does the magnetic force do no work on Q?

Because the force is always perpendicular to the velocity(direction of motion), the Magnetic force can do no work on q. W= Fv⋅∆rv=0since B-field cannot change the Kinetic Energy of a moving particle, but can change its direction of motion.

What is the magnetic force in a straight current carrying rod?

The resultant force is thus perpendicular to the direction of the velocity and the magnetic field, the direction of the magnetic field is predicted by the right-hand thumb rule. In the case of static charges, the total magnetic force is zero. Let us now discuss the force due to the magnetic field in a straight current-carrying rod.
