Quick Answer: When A Current Carrying Coil Is Placed In A Magnetic Field?

When a coil carrying current is set?

When current carrying coil is placed in the magnetic field torque acts on the coil.

The torque acting on the coil will be zero if the coil and the magnetic field are perpendicular.

Thus it orients such that the plane of coil is perpendicular to the field direction..

Why can’t magnetic field lines cross?

TWO MAGNETIC FIELD LINES CANNOT INTERSECT EACH OTHER BECAUSE IF THEY INTERSECT THEN THERE SHOULD BE TWO TANGENTS AT A POINT , WHICH REPRESENTS TWO DIRECTION OF MAGNETIC FIELD AT A POINT , AND IT IS NOT POSSIBLE. … Because that would imply that the magnetic field has two different directions at the same point.

What is torque in magnetic field?

A magnetic field exerts a torque which tries to align the normal vector of a loop of current with the magnetic field. The size of the torque on a loop of current is torque = (# turns) * (current) * (loop area) * (mag field) * sin(theta) where theta is the angle between the magnetic field and the loop’s normal vector.

How do you determine the direction of a magnetic field?

We can remember this diagram using the right-hand rule. If you point your pointer finger in the direction the positive charge is moving, and then your middle finger in the direction of the magnetic field, your thumb points in the direction of the magnetic force pushing on the moving charge.

What is the formula to find the force on a rectangular current carrying coil?

The force on a current-carrying wire in a magnetic field is F = IlB sin θ.

Why is the magnetic field made radial?

The radial magnetic field is applied to a moving coil galvanometer to produce a constant torque on the coil. It is applied to measure the relation between the current and the angle which is non-linear such that the current cannot be measured easily.

What is the position of the loop when the current is maximum?

What is the position of the loop when the current is maximum? The maximum current is when the loop is halfway into the region of the field. The maximum current is when the loop is at the beginning of the region of the field.

Under what condition torque on current loop is zero?

The torque on a current loop is zero if the angle between the positive normal and the magnetic field is either θ=0 or θ=180∘.

When a current carrying coil is placed in the magnetic field?

So, in the same way, when a cuurent carrying coil is kept in a magnetic field, three orientations are possible. When the coil is kept parallel to the field i.e., the area vector(vector associated with the area;perpendicular to the area) of the coil is kept parallel or antiparallel to the field.

What happens when a current carrying rectangular coil is placed in a magnetic field?

As the current carrying conductor experiences a force when placed in a magnetic field, each side of a current carrying rectangular coil experiences a force in a magnetic field. … the direction of force is perpendicular to the plane containing PQ and B.

What happens when a current carrying conductor is placed in a magnetic field Class 10?

When a current carrying conductor is placed in a magnetic field,the conductor experiences a force. (6) Reverse the direction of current flowing through the rod and observe the direction of its displacement.It is now towards the right. …

What happens when you place an iron nail in a current carrying coil?

Answer: When the iron strip is in contact with the screw, the current flows through the coil which becomes an electromagnet. It then, pulls the iron strip. In the process, the hammer at the end of the strip strikes the gong of the bell to produce a sound.

What is the condition of an electromagnetic induction?

[1] There should be relative motion between the coil of wire & magnet. [2] When a magnet is moved inward and outward in magnetic field & change in magnetic frequency occur due to which current is induced.

When a coil is placed perpendicular to the magnet the force exerted on the coil will be?

If the perpendicular to the coil is at an angle θ to the field direction, then the torque exerted on the coil is Fd where d = a sin q. where A = ab, the area of one face of the coil. The minimum value of the torque is zero, when θ = 0.

What happens when a current carrying conductor is placed in a uniform magnetic field?

When a current-carrying conductor is placed in a magnetic field, a mechanical force is exerted on the conductor which can make the conductor move.

When you immerse a current carrying coil in a magnetic field is there a net force on the coil?

The Torque on a Current Loop A uniform magnetic field exerts no net force on a current loop but it does exert a net torque. Let’s say the magnetic field is in the plane of the loop and is parallel to two sides.

Why is there no current produced when the magnetic field and the coil is in the same plane ie parallel )?

When the magnetic field and the coil is in the same plane, the magnetic field is not perpendicular to the current and hence fields do not cause any effect on the coil. … increasing the magnetic field lines increases the strength of the induced emf. the coils move very fast and hence leading to production of more current.
