Do all parts of a magnet have the same force?
The simple answer is yes. The magnetic field, as with gravity, appears to emanate from the centre point. At a given distance and without interference, the magnetic field would be the same strength.
What is magnetic field strength measured in?
Gauss
What does the magnetic flux per unit area indicate?
the strength of a magnetic field
What is the relationship between magnetic force and distance?
-- A current flowing through a conductor creates a magnetic field around the conductor. -- Moving a conductor through a constant magnetic field creates a current in the conductor. -- If there's a conductor sitting motionless in a magnetic field, a current flows in the conductor whenever the strength or direction of the magnetic field changes.
Is a device that can detect changes in the strength of the magnetic field?
answer
Does shape effect the magnetic repulsion between two magnets?
The further the magnets, the lesser the attraction/repulsion.
What is magnetic field strength?
Earth's magnetic field strength at the equator is about 30 microtesla.
Why is the zeeman effect used by astronomers?
It's used to determine the magnetic field strength of stars. That's not really a "why", though. I suppose the "why" would be "because they want to know the magnetic field strength of stars".
If the strength of the magnetic field at B is 6 units the strength of the magnetic field at A is?
3 units
How does temperature affect magnets?
Heat, because it affects magnetic molecules, causes a drop in magnetic field strength. Cooling a magnet has the opposite effect: reducing the resistance in the molecules and increasing the net field strength.
What is the effect of adding more coils of wire to an electromagnetic?
Increasing the coils will increase the strength of the magnetic field.
How does distance affect magnetism?
Magnetic field strength (H) is defined as the magnetomotive force per unit length, and is expressed in amperes per metre (often spoken as 'ampere turns per metre') in SI. An older, and far more descriptive term, is 'magnetomotive force gradient'.The 'closeness' or intensity of a magnetic field's flux lines, on the other hand is termed magnetic flux density(B), expressed in teslas in SI.There is a complex relationship between magnetic field strength and flux density, because of a property exhibited by ferromagnetic materials, called 'hysteresis'. In general, as the magnetic field strength applied to a sample of unmagnetised ferromagnetic material increases, the resulting flux density also increases (but not linearly) until saturation is reached, at which point any further increase in magnetic field strength will have no effect whatsoever on the flux density. If the magnetic field strength is then reduced, the flux density will also reduce (again, not linearly), but when the magnetic field strength reaches zero amperes, a certain amount of flux density remains.So to answer your question, you really need to study what's known as the B-H or magnetising curve for a sample of ferromagnetic material -this will show you exactly what the relationship between magnetic field strength and flux density for any give ferromagnetic material.
Is magnetic field strength a vector quantity?
When one refers to the strength of a magnetic field, they're usually referring to the scalar magnitude of the magnetic field vector, so no.
What is the difference between magnatic field strength and pole strength?
Pole strength is ability of poles to produce lines of force where is field strength is force which a magnetic poles experiences when places in magnetic field.
What do strength mean?
here strength means magnetic field strength
What does an eletromagnet do in a motor?
Provide amoving magnetic force field.
Do all parts of a magnet have the same force?
The simple answer is yes. The magnetic field, as with gravity, appears to emanate from the centre point. At a given distance and without interference, the magnetic field would be the same strength.
