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 determines the strength of the magnetic field when current flows through a conducter?

The strength of the magnetic field around a conductor carrying current is determined by the amount of current flowing through the conductor. The greater the current, the stronger the magnetic field. Additionally, the shape and orientation of the conductor also play a role in determining the strength of the magnetic field.


How does distance affect magnetic fields?

Distance affects magnetic fields in the sense that the strength of the magnetic field decreases as the distance from the source increases. This relationship follows an inverse square law, meaning that the magnetic field strength reduces rapidly as distance increases. As a result, the influence and impact of a magnetic field weaken with greater distance from its source.


Why is the magnetic field strength greater inside a current carrying wire than about a straight section of wire?

The magnetic field strength is greater inside a current-carrying wire because the magnetic field lines produced by the current are concentrated within the wire due to the close proximity of the electric charges moving through it. In contrast, around a straight section of wire, the magnetic field lines spread out into the surrounding space, resulting in a weaker magnetic field intensity.


In an electromagnet the magnetic forces increase as increases?

It increases as the current increases.


Which one is greater yield strength or breaking strength?

The breaking strength is always greater than the yield strength.


What happens when an electromagnet is increase?

When an electromagnet is increased in strength by increasing the current flowing through it, the magnetic field it produces becomes stronger. This results in a greater magnetic force exerted on nearby magnetic materials and a stronger attraction or repulsion between the electromagnet and other magnets.

What is the centimeters when the magnet and metal paper clip is a strong magnetic?

When a magnet attracts a metal paper clip with strong magnetic force, there is no specific measurement in centimeters. The strength of the magnetic force depends on the properties of the magnet and the paper clip, such as their size, material, and distance from each other.


What are two factors whirch can enhance electron deflection in magnetic field?

Increasing the strength of the magnetic field and increasing the velocity of the electron are two factors that can enhance electron deflection in a magnetic field. This is because a stronger magnetic field exerts a greater force on the electron, while a higher velocity leads to a larger deflection due to the interaction with the magnetic field.


How could i test and compare the strength of two different magnets?

To test and compare the strength of two different magnets, you can use a device called a Gaussmeter to measure their magnetic field strength. Place the magnets at the same distance from the Gaussmeter and record the readings. The magnet with the higher reading indicates greater strength.


What does force between two magnets depend on?

The force between two magnets is primarily dependent on the strength of the magnets' magnetic fields, the distance between the magnets, and the orientation of the magnets. In general, the force increases with stronger magnetic fields and decreases with greater distance. The force is also influenced by the alignment of the magnetic poles.
