How do you calculate the length of a magnetic field?
mg=IlB. Thus, I=mglB=(0.010kg9.8m/s2)(0.50m)(0.50T)=0.39A. This large magnetic field creates a significant force on a length of wire to counteract the weight of the wire.
What is the length of magnetic field?
The unit of force is Newtons (N), the unit of current is Amperes (A), the unit of length is meters (m), and the unit of magnetic field is Teslas (T). Magnetic Force Formula (Current-Length) Questions: 1) A copper wire is carrying a current of 4.00 A through a uniform magnetic field with magnitude 2.20 T.
What does B stand for in F bil?
by vectors v and B in a direction given by the right-hand rule. F = BIL (f=force, b=magnetic field, i=current, l=length of conductor)
What is L in magnetic field?
l = Length of the current carrying conductors parallel to each other.
Does magnetic field depend on length?
The magnetic field inside a tightly wound, long solenoid is B = µ0 ni. It suggests that the field does not depend on the total length of the solenoid, and hence if we add more loops at the ends of a solenoid the field should not increase.
What is the formula of Bil?
Derive F = BIL by starting with a single charge formula F = qvB and recognizing that current is simply I = Q/t… Derive F = BIL by starting with a single charge formula F = qvB and recognizing that current is simply I = Q/t.
What is F BIL sin θ?
F = B I L sin ( θ ) {\displaystyle F=BIL\sin(\theta )} F is the force being undergone by the current – measured in Newtons(N). B is the magnetic field strength (or flux density) of the field the charge is in (I.e The number of magnetic field lines per unit area) – measured in Teslas (T).
What is the relation between magnetic moment and magnetic field?
The magnetic field of a magnetic dipole is proportional to its magnetic dipole moment. The dipole component of an object’s magnetic field is symmetric about the direction of its magnetic dipole moment, and decreases as the inverse cube of the distance from the object.
What is magnetic moment?
Definition of magnetic moment : a vector quantity that is a measure of the torque exerted on a magnetic system (such as a bar magnet or dipole) when placed in a magnetic field and that for a magnet is the product of the distance between its poles and the strength of either pole.
What is v in magnetic field?
Moving electric charges produce magnetic fields. Magnetic fields exert forces on other moving charges. The force a magnetic field exerts on a charge q moving with velocity v is called the magnetic Lorentz force.
What are factors on which magnetic field depends?
Strength of the magnetic field Number of the turns in the coil Relative speed between the coil and the magnet Physics
- Strength of the magnetic field.
- Number of the turns in the coil.
- Relative speed between the coil and the magnet.
What are the factors depending on magnetic field?
The magnitude of magnetic field produced by a current carrying circular loop depends upon: The current passing through the circular loop-directly proportional. The radius of circular loop-inversely proportional. Number of turns of the wire in the circular loop-directly proportional.
Are tesla and gauss the same?
This means that Gauss can be solely expressed using centimetre, gram, and second. Tesla is used to expressing magnetic flux density in the SI unit, which is a seven-dimensional system….Conversion of Gauss and Tesla.
| Units | Values |
|---|---|
| 1 Tesla in gauss | 1tesla = 10,000 gauss |
| 100 gauss to Tesla | 100 gauss= 0.01 Tesla |
How do you convert tesla to Newton?
From Wikipedia: A particle carrying a charge of 1 coulomb and passing through a magnetic field of 1 tesla at a speed of 1 meter per second perpendicular to said field experiences a force with magnitude 1 newton, according to the Lorentz force law. So 1 Tesla = 1N / (1C .
What is L in Bilsin Theta?
L=length of wire/conductor. F=magnetic field strength. Sin(Theta)= the angle made between the conductor and the field.
What is Theta in magnetic force?
where theta is the angle between the wire and the magnetic field. The direction of the vector L is the same as the direction of the current through the wire. Because forces are easy to measure, it is the force exerted on a current-carrying wire which is used to define the SI unit of current, the ampere.
What is the number of magnetic field lines?
For example, the number of field lines through a given surface is the surface integral of the magnetic field. Various phenomena “display” magnetic field lines as though the field lines were physical phenomena. For example, iron filings placed in a magnetic field form lines that correspond to “field lines”.
Is the earth’s magnetic field constant?
Earth’s magnetic field is not constant—the strength of the field and the location of its poles vary. Moreover, the poles periodically reverse their orientation in a process called geomagnetic reversal. The most recent reversal occurred 780,000 years ago. Record-high fields
How does the strength of the magnetic field depend on distance?
The strength of the magnetic field decreases with distance from the wire. (For an infinite length wire the strength is inversely proportional to the distance.) A Solenoid with electric current running through it behaves like a magnet.
What is the magnetic field of a permanent magnet?
The magnetic field of permanent magnets can be quite complicated, especially near the magnet. The magnetic field of a small straight magnet is proportional to the magnet’s strength (called its magnetic dipole moment m).
