Increasing the current flowing through the coil will increase the magnetic field produced by the coil, which in turn will increase the magnetic flux density inside the coil. This relationship is described by Ampere's law which states that the magnetic field is directly proportional to the current flowing through the coil.
What else can I help you with?
What happens to the sideways force when flux density increases?
When flux density increases, the force experienced by a current-carrying conductor due to a magnetic field (sideways force in this case) will also increase. This is because the force is directly proportional to the magnetic flux density and the current in 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.
How can you increase strength of solenoid?
You can increase the strength of a solenoid by increasing the number of turns in the coil, increasing the current flowing through the coil, using a core material with higher magnetic permeability, and optimizing the design for maximum magnetic flux density.
Is you true the magnetic field around an electromagnet can be made stronger by increasing current or decreasing the number of coils around the iron core?
Yes, increasing the current flowing through the coils of an electromagnet will strengthen the magnetic field. Additionally, decreasing the number of coils around the iron core can also enhance the magnetic field strength due to increased current density.
What is the diagram of a magnetic field and how does it illustrate the direction and strength of the magnetic field lines?
A magnetic field diagram shows the direction and strength of magnetic field lines around a magnet or current-carrying wire. The lines indicate the direction a compass needle would point if placed in the field. The density of the lines represents the strength of the magnetic field, with closer lines indicating stronger fields.

When a magnetic field is parallel to a current-carrying wire what is the force on the wire?
When a magnetic field is parallel to a current-carrying wire, there is no force acting on the wire. This is because the magnetic force on a current-carrying wire is perpendicular to both the current and the magnetic field.

What are the three ways in which the strength of induced emf in electric generator can be increased?
Increasing the number of turns in the coil to enhance the magnetic flux linkage. Using stronger magnets or increasing the speed of rotation to boost the magnetic field strength. Utilizing a core with higher magnetic permeability to enhance the flux density and, consequently, the induced emf.
What is the limit for magnetic field developed for a DC machine?
The magnetic field used in machines is quantified in terms of its flux density (symbol: B), expressed in teslas. The flux density is established by the magnetic field strength (H), expressed in amperes per metre, set up in the field windings.As the magnetic field strength increases, the flux density increases until it reaches saturation. This is the point when the magnetic domains within the magnetic circuit are all aligned. At this point, any further increase in magnetic field strength will fail to increase the flux density.So saturation of the magnetic circuit limits the flux density of the field.
What kind of density current is caused by muddy rapidly flowing mixture of sediment and water?
A turbidity current is a density current that occurs when mud or silt mixes with seawater. This is the result of the increase in the density of the water itself.
What is Magnetic field on the axis of a current carring circular coil?
A current circulating in a hollow copper coil (solenoid) produces a magnetic field equal to the permeability times the turns density times the current. B = μ x n x I * B is the magnetic field measured in Tesla * μ is the relative permeability of the solenoid's core which is air in this example and have a value approximated to 1.25663706E-6 * n is the turns density which equals the number of turns divided by the solenoid length n = N/L where L is measured in meters. * I is the current flowing within the solenoid and measured in Amperes
How do you calculate the magnetic field strength in an injector cyclotron?
- Magnetic field strength is the intensity of a magnetic field at a given location. Historically, a distinction is made between magnetic field strength H, measured in ampere/meter, and magnetic flux density B, measured in tesla. Magnetic field strength is defined as the mechanical force (newton) on a wire of unit length (m) with unit electric current(A). The unit of the magnetic field, therefore, is newton/ (ampere x meter), which is called tesla. The magnetic field may be visualized by magnetic field lines. The field strength then corresponds to the density of the field lines. The total number of magnetic field lines penetrating an area is called magnetic flux. The unit of the magnetic flux is tesla x m2 = weber. The older units for the magnetic flux, maxwell = 10-8 weber, and for the magnetic flux density, gauss = maxwell / cm2 = 10-4 tesla, are not to be used any more. Magnetic flux density diminishes with increasing distance from a straight current-carrying wire or a straight line connecting a pair of magnetic poles around which the magnetic field is stable. At a given location in the vicinity of a current-carrying wire, the magnetic flux density is directly proportional to the current in amperes. If a ferromagnetic object such as a piece of iron is brought into a magnetic field, the "magnetic force" exerted on that object is directly proportional to the gradient of the magnetic field strength where the object is located. ------------------------------------------------------------------- B=μH Magnetic field in Solenoid B=μnI where n is turns/m So H=nI --------------------------------------------
