How do you determine the direction of a magnetic force?

How do you determine the direction of a magnetic force?

We can remember this diagram using the right-hand rule. If you point your pointer finger in the direction the positive charge is moving, and then your middle finger in the direction of the magnetic field, your thumb points in the direction of the magnetic force pushing on the moving charge.

Does flux have a direction?

These fluxes are vectors at each point in space, and have a definite magnitude and direction.

What determines which direction the iron bar moves in a solenoid?

The small magnetic field created around the conductor has a definite direction with both the “North” and “South” poles produced being determined by the direction of the electrical current flowing through the conductor.

What will happen when the direction of current in the solenoid is reversed?

Answer: The magnetic field generated is always perpendicular to the direction of the current and parallel to the solonoid. Hence if we reverse the current the direction of magnetism also reverses. In other words the magnetic poles gets reversed (North pole becomes south pole and the south pole becomes the north pole).

How do you determine the direction of the magnetic field in a current carrying solenoid?

The direction of magnetic field due to a current carrying solenoid can e found out using right hand grip rule. According to this rule, the thumb points towards the N-pole when the current flows in the direction of the curl of the fingers.

Why is there no magnetic field outside the solenoid?

The magnetic field lines follow the longitudinal path of the solenoid inside, so they must go in the opposite direction outside of the solenoid so that the lines can form a loop. In order for the total number of field lines to be conserved, the field outside must go to zero as the solenoid gets longer.

What is the magnitude and direction of the magnetic field inside a current carrying solenoid?

B = mu(o) n I. For direction of Magnetic field, we can use Right hand thumb rule.

Where is the solenoid strongest?

The magnetic field is strongest inside the coil of a solenoid. Inside the coil of a solenoid the magnetic field lines are uniform and tightly packed…

What are the properties of solenoid?

• a long tightly wound helical coil insulated metallic wire is called solenoid.
• the magnetic field produce inside the solenoid( also called core of solenoid ) is Constant.
• a circular solenoid is called toroid.
• the strength of magnetic field increase if current flowing in solenoid increase.

Do solenoids push or pull?

In Pull type solenoids, the plunger is pulled into the solenoid coil when the coil is energized. In Push type solenoids, the same is true, however, the plunger has a shaft extension which then pushes out through a hole in the end of the solenoid case.

How do you increase the power of a solenoid?

The strength of the magnetic field around a solenoid can be increased by:

1. increasing the number of turns on the coil.
2. increasing the current.
3. placing an iron core inside the solenoid.
