What is the magnetic force on conductor?
The magnetic force on current-carrying conductors is given by. F=IlBsinθ F = I l B sin where I is the current, l is the length of a straight conductor in a uniform magnetic field B, and θ is the angle between I and B. The force follows RHR-1 with the thumb in the direction of I.
What is the formula for the magnetic force on a current carrying conductor?
Sal derives the formula F=ILB to determine the force on a current carrying wire.
What is the magnetic force acting on the loop?
The net force on a current loop in a uniform magnetic field is zero.
How do you find the force acting on a conductor?
Example
- 5.0 cm = 5 ÷ 100 = 0.050 m.
- force on a conductor carrying a current = magnetic flux density × current × length.
- force = 0.60 × 0.75 × 0.050.
- force = 0.0225 N.
How do you calculate magnetic force?
Magnetic Force
- The force is perpendicular to both the velocity v of the charge q and the magnetic field B.
- The magnitude of the force is F = qvB sinθ where θ is the angle < 180 degrees between the velocity and the magnetic field.
- The direction of the force is given by the right hand rule.
What is the magnetic moment of an electron due to its motion in a circular orbit?
Answer. Answer: The value of the electron magnetic moment is approximately −9.284764×10−24 J/T.
What is formula of magnetic moment?
Magnetic Moment Formula: The magnetic moment is a vector relating torque of an object to the magnetic field. This is mathematically represented as: τ = m × B. Where, τ is the torque acting on the dipole.
How do you calculate magnetizing force?
Don’t confuse magnetomotive force with magnetic field strength (magnetizing force)….Magnetomotive Force.
| Quantity | Unit | Formula |
|---|---|---|
| Magnetomotive force | amperes | Fm = H × le |
| Electromotive force | volts | V = E (Electric field strength) × l (distance) |
How does the magnetic moment of an electron in a circular orbit of radius R and moving with speed v change when the frequency of revolution is doubled?
An electron revolving in a circular orbit of radius ‘r’ with velocity ‘V’ and frequency ‘v’ has orbital magnetic moment ‘M’. If the frequency of revolution is doubled then the new magnetic moment will be 2 M. if is doubled, M will be doubled. ∴ if ω is doubled, M will be doubled.
What is the magnetic moment of a revolving electron in a circular orbit?
Magnetic moment of an electron : μ=IA=2πrev×πr2=2evr.
What is the magnetic moment of force?
Magnetic moment, also known as magnetic dipole moment, is the measure of the object’s tendency to align with a magnetic field. “Magnetic Moment is defined as magnetic strength and orientation of a magnet or other object that produces a magnetic field.” The magnetic moment is a vector quantity.
