1. ## Solenoids as Magnetic Field Sources | Solenoid Magnetic Field Calculation

• Solenoid. A long straight coil of wire can be used to generate a nearly uniform magnetic field similar to that of a bar magnet.
• The expression is an idealization to an infinite length solenoid, but provides a good approximation to the field of a long solenoid.

3. ## Electromagnetism online calculation: Solenoid properties - Inductance and magnetic B-field.

• The magnetic field strength for a solenoid is given by B=μI*n/l. The inductance of a solenoid is close to L=μr²n²π/l, but diverges increasingly from this estimation as the length becomes shorter relative to the radius.

6. ## Magnetic Fields due to a Solenoid

• In a solenoid, a large field is produced parallel to the axis of the solenoid (in the z-direction in figure 2). Components of the magnetic field in other directions are cancelled by opposing fields from neighbouring coils.

8. ## Evaluation copy | Part II How is the Magnetic Field in a Solenoid Related to the Spacing of the Turns?

• In this lab we will explore factors that affect the magnetic field inside the solenoid and study how the field varies in different parts of the solenoid. By inserting a Magnetic Field Sensor between the coils of the Slinky, you can measure the magnetic field inside the coil.

10. ## A Current-Carrying Coil as a Magnetic Dipole | Magnetic field strength inside an ideal solenoid We can use Ampere’s law to calculate the magnetic field strength inside an ideal solenoid. The cross-sectional view of an ideal solenoid is shown.

• However, a permanent magnet can never be turned off. The magnetic field of a solenoid can be turned off simply by turning the current off. Solenoids form the basis of many "electromagnets" that can be controlled by currents.
