Where Is Maximum Torque Produced In Magnetic Field?

The torque τ is maximum when the normal of the loop is perpendicular to the magnetic field , and zero when the normal is parallel to the field.

When torque is maximum in magnetic field?

A current-carrying coil kept in a magnetic field experiences a torque, which is the cross product of the magnetic moment and the field vector. Hence, the torque is maximum when the dipole moment is perpendicular to the field , and zero when it’s parallel or antiparallel to the field.

How torque is produced in magnetic field?

Motors are the most common application of magnetic force on current-carrying wires. Motors have loops of wire in a magnetic field. When current is passed through the loops, the magnetic field exerts torque on the loops , which rotates a shaft. Electrical energy is converted to mechanical work in the process.

Where is the strength of a magnetic field maximum?

And therefore magnetic force is maximum at both the poles of the magnet compared to the centre of magnet.

How do you get the maximum torque?

Note that the torque is maximum when the angle is 90 degrees . A practical way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force. The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force.

How do you calculate magnetic torque?

The torque on the dipole is τ = μ×B , where B is the external magnetic field. The magnitude of this torque is μB sinθ, where θ is the angle between B and μ (that’s just definition of cross-product).

What is the maximum torque on a rectangular coil?

The torque on the coil will depend on the orientation of the coil. If the coil’s plane is parallel to the magnetic field, then the torque on the coil will be maximum (NIBA). If the coil’s plane is perpendicular to the magnetic field then the torque on the coil will be minimal or zero.

How do you calculate minimum torque?

To calculate load torque, multiply the force (F) by the distance away from the rotational axis , which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.

How do you calculate current torque?

1. Torque is nothing but a momentary force developed at the time of force is applied to the motor. The unit of torque is N.m (Newton-meter). ...
2. T = V x I x pf / (2 x pi x N _{( rpm )} / 60)
3. I => Input AC Current in amps.

Is Tesla a SI unit?

The tesla (symbol T) is the derived SI unit of magnetic flux density , which represents the strength of a magnetic field. One tesla represents one weber per square meter.

Why field strength is maximum at the poles?

The magnetic force or attraction is is greater where the field lines are crowded. Since all the magnetic field lines generate from the poles, the crowd of field lines is maximum near pole. ... this is because the poles are active sources of magnetic field lines .

What is the maximum magnetic field?

What is the maximum possible magnetic field allowed in our universe? According to two theoretical physicists in Russia and Israel, it is 10 ⁴² Gauss — a value that is a billion times smaller than the previous estimate for the upper limit.

Is there a maximum magnetic field?

There is no firmly-established fundamental limit on magnetic field strength , although exotic things start to happen at very high magnetic field strengths. ... Therefore, electric charges tend to spiral around magnetic field lines and be pushed away from regions where magnetic field lines bunch up.

Does higher torque mean faster acceleration?

A car with more hp than torque will always be quicker since this gives a car acceleration and speed. ... This is why low-end torque becomes important for better acceleration in many scenarios. Higher torque doesn’t mean one vehicle will necessarily be faster than another, though.

Is the higher the torque the better?

Horsepower means your car can go faster, and torque means...? Torque, simply, is the ability of a vehicle to perform work — specifically, the twisting force applied by the crankshaft. ... Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms .

What force does not cause any torque?

Any force that is along a line which passes through the axis of rotation produces no torque. Note that torque is a vector quantity, and, like angular displacement, angular velocity, and angular acceleration, is in a direction perpendicular to the plane of rotation.
