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


Does the number of coil of wire in an electromagnet affect its magnetic strength?

yes,the more the coils the more the strength it collects


What are 3 factors which affect the magnitude of magnetic force on current-carrying conductors?

What do you mean by magnetic affect of electric?

The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.


What happens in the electric bell when aluminium strip is used instead of iron strip?

Using an aluminum strip instead of an iron strip in the electric bell will affect the magnetic properties and the strength of the electromagnet. Aluminum is not as magnetic as iron, so the electromagnet will not be able to attract the hammer to strike the bell as effectively. This may result in a weaker sound or the bell not ringing at all.


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.


How does the number of wraps of wire affect the strength of an electromagnet?

The more turns of wire in an electromagnet the stronger the magnetic field.


What factors may affect the strength of the magnetic field generated around the coil?
