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).

How did the size of the current in the coil affect the strength of the elctromagnet?
The strength of an electromagnet is directly proportional to the current passing through the coil. Increasing the current will increase the strength of the magnetic field produced by the electromagnet, whereas decreasing the current will weaken the magnetic field.
How do the size of the current in the coil affect the strength of a electromagnet?
The strength of an electromagnet is directly proportional to the current flowing through the coil. Increasing the current in the coil increases the magnetic field strength produced by the electromagnet. This means that increasing the size of the current in the coil will make the electromagnet stronger.
What does current carrying wire produce?
A current-carrying wire produces a magnetic field around it. This magnetic field strength is directly proportional to the amount of current flowing through the wire.
What would happen to the strength of the field if the current was increased?
If the current in a wire is increased, the strength of the magnetic field around the wire would also increase. This is because magnetic field strength is directly proportional to the amount of current flowing through the wire.
Does electric current create magnetic fields?
Yes, electric current does create magnetic fields

What is the magnetic effects of electrical current?
When an electrical current flows through a conductor, it creates a magnetic field around the conductor. This phenomenon is known as electromagnetism. The strength of the magnetic field is directly proportional to the current flowing through the conductor.
What is the relationship between the surface current density and the magnetic field on a current sheet?
The surface current density on a current sheet is directly proportional to the magnetic field it produces. This means that as the surface current density increases, the strength of the magnetic field also increases.
What is the strength and direction of the magnetic field generated by a finite current-carrying wire?
The strength of the magnetic field generated by a finite current-carrying wire is directly proportional to the current flowing through the wire and inversely proportional to the distance from the wire. The direction of the magnetic field can be determined using the right-hand rule, where the thumb points in the direction of the current and the fingers curl in the direction of the magnetic field.
How does the strength of the magnetic field around a wire change if the current in the wire is increased from 0.25 A to 1.75 A?
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.
Why do the magnetic forces acting on the coil change as the current running through the coil changes?
The magnetic forces acting on the coil change with the current because the strength of the magnetic field produced by the current in the coil is directly proportional to the current flowing through it. As the current changes, the magnetic field strength changes, leading to a change in the magnetic forces acting on the coil.
Can electricity easily produce a magnetic field?
Yes, electricity can easily produce a magnetic field by running current through a conductor. The magnetic field strength is directly proportional to the amount of current flowing through the conductor.
In an electromagnet the magnetic forces increase as this increase?
In an electromagnet, the magnetic forces increase as the current flowing through the coil increases. This is because the magnetic field strength is directly proportional to the amount of current flowing through the coil.
