How magnetic field lines look in hollow cylindrical electromagnet?
Inside the hollow cylindrical electromagnet ("solenoid"), the magnetic field lines are straight, parallel to each other, and parallel to the axis of the cylinder. They get more complicated at the ends, but the above statement is good for a solenoid of infinite length, which has no ends, and is a good approximation in the center of a real one.
Why is the magnetic field produced by a cylindrical solenoid is similar to a cylindrical permanent magnet?
Simple Answer:The shape of the magnetic field of a uniformly wound solenoid is very nearly identical to the field produced by a uniformly magnetized permanent magnet with the same physical shape as the solenoid.For the Experts:This is a consequence of the mathematical equivalence of the source of the magnetic field as created by a current and the source of a magnetic field as created by the curl of the magnetization density of permanent magnet.
Where is the strongest field in a toroidal magnet?
according to the ampere's law . magnetic field is strongest in a loop or a plane. and about toroid the magnetic is strongest in the coil where the wire is rotated around it . Magnetic field is minimum inside and outside the toroid.
Is earth's magnetic field in an closed iron box more than the magnetic field outside the box?
No, the Earth's magnetic field cannot be contained within a closed iron box. Iron is a ferromagnetic material that can distort and redirect magnetic field lines, but it cannot increase the total magnetic field strength. The magnetic field inside the box would be the same as that outside the box.
Why magnetic field outside the solenoid is zero?
The magnetic field outside a solenoid is nearly zero due to the cancellation of magnetic fields generated by individual current-carrying loops within the solenoid. These loops produce magnetic fields that point in opposite directions, resulting in a net magnetic field of zero outside the solenoid. Additionally, the magnetic field lines tend to stay within the solenoid due to the high permeability of the material surrounding the coils, further reducing the magnetic field outside the solenoid to negligible levels.

What is the significance of the z component of the magnetic field outside the solenoid in relation to its overall magnetic field characteristics?
The z component of the magnetic field outside a solenoid is significant because it determines the direction and strength of the magnetic field in that region. It contributes to the overall magnetic field characteristics of the solenoid by influencing the field's orientation and intensity outside the solenoid.
What is the electric field strength just outside of the hollow insulating shell?
The electric field strength just outside of the hollow insulating shell is zero.
How do magnetic fields from currents in a wire interact with a cylindrical shell?
When a current flows through a wire, it creates a magnetic field around it. This magnetic field can interact with a cylindrical shell by inducing currents in the shell, which can in turn create their own magnetic fields. The interaction between the magnetic fields from the wire and the shell can affect the distribution of currents and magnetic fields in the system.
How is magnetic field made radial in a moving coil galvanometer?
The magnetic field in a moving coil galvanometer is made radial by surrounding the coil with a cylindrical magnetic core. When current flows through the coil, it creates a magnetic field perpendicular to the coil. This magnetic field interacts with the radial magnetic field of the core, causing a torque on the coil that deflects the pointer.
Is earth's magnetic field in an closed iron box more than the magnetic field outside the box?
No, the Earth's magnetic field cannot be contained within a closed iron box. Iron is a ferromagnetic material that can distort and redirect magnetic field lines, but it cannot increase the total magnetic field strength. The magnetic field inside the box would be the same as that outside the box.
What are fero magnetic substance?
Ferromagnetic substances are materials that have strong magnetic properties and can be magnetized. They include iron, nickel, and cobalt. These materials can retain their magnetic properties even after the external magnetic field is removed.
What are the properties and applications of a hollow magnetic sphere?
A hollow magnetic sphere is a sphere made of magnetic material with an empty space inside. Its properties include the ability to attract and repel other magnetic objects, as well as the ability to create a magnetic field. Some applications of a hollow magnetic sphere include use in magnetic resonance imaging (MRI) machines, magnetic levitation systems, and as a component in magnetic sensors and actuators.
Why the coil is like cylindrical shape in moving coil galvanometer?
The coil in a moving coil galvanometer is designed in a cylindrical shape to create a uniform magnetic field when placed between the poles of a magnet. This shape allows for a consistent and efficient interaction between the coil and the magnetic field, enabling accurate measurement of current. Additionally, the cylindrical design facilitates the rotation of the coil within the magnetic field, which is essential for converting the electrical signal into a readable mechanical deflection on the scale.
Where is the strongest part of magnetic field in current carrying wire?
The strongest part of the magnetic field in a current-carrying wire is near the wire itself, specifically surrounding the wire in a cylindrical pattern. The strength of the magnetic field decreases as you move further away from the wire.
