According to Ampere's Law, the strength of the magnetic field around a long, straight wire carrying current is directly proportional to the current and inversely proportional to the distance from the wire at which it is measured. Assuming fixed distance from the wire (meaning that you're measuring in the same place), if you increase the current by 1.75/.25= 7 times, you will also increase the magnetic field by 7 times.
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
The strength of an electromagnets magnetic field depends on:The type of core metalThe ability of the wire to carry current (its material and thickness)The number of turns of the wiring around the coreThe voltage/current of the electricity going through the wire.
More currents, or more loops.
Electric current causes magnetic field around conductor by producing a moving electric charges and the intrinsic magnetic moments of an elementary particles that is associated with a fundamental quantum property.
One way to increase the strength of a copper electromagnet is by adding another coil. Another way is by wrapping the copper coil around a nail made of iron.Adding more loops to the wireWrapping the copper wire around an iron nailIncreasing the 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
-- 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.

The illustration on the HowStuffWorks website is probably the easiest to understand. As you add coils to the electromagnet you have more and more magnetic field traveling in a certain vector (depending on which way current is flowing). It's much like a lot of physics...as you add horses to a plow the force is increased. As you add coils to an electromagnet the magnetic field increases. As I said, check out this link for better understanding. http://science.howstuffworks.com/electromagnet4.htm\ A wire with an electric current passing through it, generates a magnetic field around it, this is a simple electromagnet. The strength of magnetic field generated is proportional to the amount of current. if we were to increase the number of coils the strength of the magnetic field would increase, also increasing the strength of the magnet
It puts an iron core around a conductor, which allows the meter's circuitry to sense the strength of the magnetic field. The strength of the field around the conductor is related to the amount of current flowing.
Magnetic field.
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.
Current passing through a wire in a magnetic field creates its own magnetic force in some direction. If you increase the current, force will be increased. If the direction of current is changed, direction of force will also be reversed. Direction of current is found by applying right hand rule.
-- 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.
yes.magnetic field present around the conductor.current and magnetic fields are inter related..with current we can produce magnetic field and vice versa
One of them is how many coils go around the electromagnet. also the amout of current flow< and the type of core material.
