Does the thickness or length of the nail affect the electro magnets strength?
yes
Why magnetic lentgh is less than geometric length of magnet?
magnetic length refers to the length of magnet which is able to produce magnetic lines from it. since whole length is not able for that magnetic length is small than geometric one
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.
How do you calculate the magnetic field strength in an injector cyclotron?
- Magnetic field strength is the intensity of a magnetic field at a given location. Historically, a distinction is made between magnetic field strength H, measured in ampere/meter, and magnetic flux density B, measured in tesla. Magnetic field strength is defined as the mechanical force (newton) on a wire of unit length (m) with unit electric current(A). The unit of the magnetic field, therefore, is newton/ (ampere x meter), which is called tesla. The magnetic field may be visualized by magnetic field lines. The field strength then corresponds to the density of the field lines. The total number of magnetic field lines penetrating an area is called magnetic flux. The unit of the magnetic flux is tesla x m2 = weber. The older units for the magnetic flux, maxwell = 10-8 weber, and for the magnetic flux density, gauss = maxwell / cm2 = 10-4 tesla, are not to be used any more. Magnetic flux density diminishes with increasing distance from a straight current-carrying wire or a straight line connecting a pair of magnetic poles around which the magnetic field is stable. At a given location in the vicinity of a current-carrying wire, the magnetic flux density is directly proportional to the current in amperes. If a ferromagnetic object such as a piece of iron is brought into a magnetic field, the "magnetic force" exerted on that object is directly proportional to the gradient of the magnetic field strength where the object is located. ------------------------------------------------------------------- B=μH Magnetic field in Solenoid B=μnI where n is turns/m So H=nI --------------------------------------------
Weight of polypropylene sheets?
The weight of polypropylene sheets depends on their length, width and thickness.
Does the thickness or length of the nail affect the electro magnets strength?
yes
The length of a part being magnetized by passing an electric current from one end to the other affect 1 permeability 2 strength of magnetic field 3 not affect magnetic field?
Permeability
Does the thickness of a string affect its sound?
Yes, and so does the length.
What are factors that affect resistance of electricity?
Temperature, thickness, length and type of wire.
Which factors affect the magnetic strength of a solenoid which is carrying an electric current?
Factors affecting the magnetic field strength of a solenoid are: - length of the solenoid - diameter of the solenoid - current through the coil around the solenoid - number of turns of the coil of current around the solenoid, usually turns of wire - material in the core
How would you Explain magnetic pole strength?
Magnet has two poles. The Pole strength depends on flux that emanate from it. The pole strength is measured in Amp-m. If we know magnetic moment the pole strength can be calculated as magneticmoment/length of magnet
A Has infinite length and length but no thickness?
A point has no length, width, or thickness. A line has infinite length but no width or thickness. A plane has infinite length and width but no thickness.
Does the length of a wire affect the strength of an electromagnet?
longer= stronger
What are the factors affecting the electromagnetic induction?
Identify factors which affect the power of electromagnet?
Does the length of sticky tape affect its strength?
yes, the smaller the length the stronger it will make the tape.
Has length no dimension no thickness?
Length IS a dimension (in space). It has no thickness.
Does the thickness or length of a nail effect the electromagnetic strength?
no it only gives more room to pick up paper clips
