If a ring of radius r is carrying current and there is an external magnetic field that is always perpendicular to the current in the ring what is the magnitude of the force acting on the ring?

On the surface, it seems net applied force on the ring would be zero. Vectors assessed at any point will sum to a value of equal but opposite sign to the vectors at a point symetrically opposite. In a perfect theoretical construct, the force vectors will "cancel out" and nothing will happen. But there may be a little more to this....

When does current carrying conductor placed in a magnetic field experiences a maximum force?
It experiences maximum force when it is placed perpendicular to the direction of magnetic field.
What are 3 factors which affect the magnitude of magnetic force on current-carrying conductors?
Electric current, magnetic field intensity, length of the conductor, angle between the electric current and magnetic field
What is definition of paramagnetic and dimagnetic materials?
A dimagnetic material produces a magnetic field that opposes an external field. A paramagnetic materia, on the other hand, produces a magnetic field that increases an external field. Dimagnetism and paramagnetism are induced when an object is placed in a magnetic field.
What is the Hall effect?
If a semiconductor carrying a current ( I ) is placed in a transverse magnetic field ( B ), an electric field ( E ) is induced in the direction perpendicular to both I & B.This is called hall effect.for full explanation visit http://www.ecematerials.com/2013/07/hall-effect.html
The magnetic field strength inside a current-carrying coil will be greater if the coil encloses a?
If the coil encloses an iron rod, then the magnetic field strength inside a current-carrying coil will be increased. This occurs because the air path in the coil is made shorter by putting in the rod. This in turn causes an increase in the field.
What is the principle of motor action?
Motor runs by the principle of Michael Faraday's Electromagnetic Induction. It is defined as "when a current-carrying conductor is located in an external magnetic field perpendicular to the conductor, the conductor experiences a force perpendicular to itself and to the external magnetic field". The direction of rotation is determined by the Right-hand Rule and is "if the right thumb points in the direction of the current in the conductor and the fingers of the right hand point in the direction of the external magnetic field, then the force on the conductor is directed outward from the palm of the right hand".

What happens to a current carrying wire in a magnetic field when it is reversed?
the wire would be deflected perpendicular to the magnetic field in the opposite direction.
When is the force experienced by a current carrying conductor placed in a magnetic field the largest?
When the conductor,magnetic field and motion are perpendicular to each other
When does current carrying conductor placed in a magnetic field experiences a maximum force?
It experiences maximum force when it is placed perpendicular to the direction of magnetic field.
Why and when does a current carrying conductor kept in a magnetic field experiences a force list factor on which the direction of this force depend State the rule which may be used to determine the di?
Current carrying conductor will have magnetic lines around it. So when it is kept perpendicular to the magnetic field then the force would be maximum. The force depends on 1. magnitude of current 2. Magnetic field induction 3. Angle between the direction of current and magnetic field. Fleming's Left hand rule is used to find the direction of force acting on the rod
What are 3 factors which affect the magnitude of magnetic force on current-carrying conductors?
Electric current, magnetic field intensity, length of the conductor, angle between the electric current and magnetic field
Why does the current carrying conductor experiences a force when it is placed in magnetic field state Fleming's left hand rule?
The force on current carrying conductor kept in a magnetic field is given by the expression F = B I L sin@ So the force becomes zero when the current carrying conductor is kept parallel to the magnetic field direction and becomes maximum when the current direction is normal to the magnetic field direction. Ok now why does a force exist on the current carrying conductor? As current flows through a conductor magnetic lines are formed aroung the conductor. This magnetic field gets interaction with the external field and so a force comes into the scene.
When a current carrying conductor is placed into a magnetic field a voltage will be generated perpendicular to both the current and the field This effect is called?
Hall Effect
What is the force between two perpendicular current carrying wires?
The magnetic force between currents moving in the oppoiste directions is repulsive.
A current-carrying wire is in a magnetic field with the direction of the current perpendicular to that of the field?
Fleming's left hand rule that explains Lorentz force would answer your queries
What determines the strength of a magnetic field?
factors on which magnetic field a bar magnet depends :- 1. pole strength of the magnet 2. medium in which the bar magnet is present(since the permittivity changes) factors on which external magnetic field(B) of a current carrying coil depends:- 1. the amount of current flowing through the conductor 2. the perpendicular distance of the point from the conductor. 3. medium in which the conductor is present(since the permittivity changes)
