Magnetic field induction B = ur uo n I
ur is relative permittivity of the core
n the number of turns
I the current through the coil
So by increasing current or the number of turns B can be increased. By using a core with larger value of ur B could be increased
Increasing the current flowing through the coil of wire around an iron bar will increase the strength of the magnetic field produced by the electromagnet. This is because magnetic field strength is directly proportional to the current flowing through the coil.
Increasing the number of turns in the coil of wire will most likely increase the strength of the magnetic field produced by an electromagnet. More turns of wire will result in a stronger magnetic field due to the increased current flowing through the coil.
An electromagnetic field can exert a force on an electron, causing it to accelerate or move in a specific direction. The direction and magnitude of the force depend on the strength and orientation of the electromagnetic field.
To increase the strength of a magnetic field, you can use a stronger magnet or increase the current flowing through a wire in an electromagnet. You can also increase the number of coils in an electromagnet to enhance its magnetic field strength. Additionally, bringing magnetic materials closer to the magnet can also increase the overall magnetic field strength.
As current in the coil increases, the magnetic field generated around the coil also increases. This stronger magnetic field results in a stronger electromagnetic force, leading to an increase in strength. According to Ampere's law, the strength of the magnetic field is directly proportional to the current flowing through the coil.
Increasing the coils will increase the strength of the magnetic field.

Increasing the voltage or decreasing the distance between the charges will increase the strength of an electric field. Additionally, increasing the amount of charge that creates the field will also increase its strength.
No, the strength of a magnetic field does not increase as you move away from the electromagnet. The strength of a magnetic field decreases with distance from the source, following the inverse square law. This means that the magnetic field weakens as you move further away from the electromagnet.
The electromagnetic wave intensity equation is given by I E2 / (2), where I is the intensity, E is the electric field strength, and is the permeability of the medium. This equation is used to calculate the intensity of electromagnetic waves by squaring the electric field strength and dividing by twice the permeability of the medium.
the same, just closer.
Increasing the strength of the magnetic field passing through the loop, increasing the number of turns in the wire loop, or increasing the speed at which the magnetic field changes can all increase the current in a stationary wire loop through Faraday's law of electromagnetic induction.
