If the coil encloses an iron rod, then the magnetic field strength inside a current-carrying coil will be increased. This occurs because the air path in the coil is made shorter by putting in the rod. This in turn causes an increase in the field.

What happens to the strength of an electromagnet when the voltage in the coils of the solenoid is decreased?

The greater the current in the coil, the stronger the magnetic field will grow. Conversely, lowering the battery voltage decreases the current, weakening the field.


How the magnetic field around a solenoid can be strengthened?

The strength of the magnetic field produced by a current carrying solenoid depends on:The number of turns - larger the number of turns, greater is the magnetism produced.The strength of the current - when current increases, magnetism also increases.Nature of 'core-material' used in making the solenoid - if we use soft-iron as a core for the solenoid, then it produces the strongest magnetism.


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 directly proportional to the coil or the current?

The strength of a magnetic field won't be directly proportional to the turns in the coil. It is more correct to say that field strength is directly proportional to current through the windings of the coil. There are some "limiting factors" that will not allow this to be a hard and fast rule, but it is essentially correct.AnswerMagnetic field strength (symbol: H) is defined as the magnetomotive force per unit length of a magnetic circuit. As magnetomotive force is the product of the current flowing through a winding and the number of turns, then, yes, magnetic field strength is proportional to both the current and the number of turns -but this is ONLY true over the straight part of the magnetisation curve (i.e. before it goes into saturation).
