There is a convenient rule called the "right hand grip rule":
If you grip your right hand around the electric conductor with your thumb pointing in the direction the current is flowing, the magnetic field rotates in the direction your remaining fingers are pointing.

How does the Earth's rotation affect the strength and direction of the magnetic field?
The Earth's rotation influences the strength and direction of its magnetic field by causing the flow of molten iron in the outer core, which generates the magnetic field. This flow is affected by the rotation of the Earth, leading to changes in the magnetic field's intensity and orientation.
What is the speed of rotation of the magnetic field called?
The speed of rotation of the magnetic field is called magnetic flux. It is a measure of the flow of a magnetic field through a particular area.
When a loop of wire is spun in a magnetic field the current changes direction how many times?
The current changes direction twice for each complete rotation of the loop in the magnetic field.
What is the direction of magnetic flux in a magnetic field?
The direction of magnetic flux in a magnetic field is from the north pole to the south pole.
How can one find the direction of the magnetic field?
To find the direction of the magnetic field, you can use a compass or a magnetic needle. The needle will align itself with the magnetic field lines, pointing towards the direction of the field.

What is the direction of the magnetic field from north to south?
The direction of the magnetic field is from north to south.
The force on an electron moving in a magnetic field will be the largest when its direction is?
perpendicular to the magnetic field direction
What is the direction of flux in a magnetic field?
The direction of flux in a magnetic field is perpendicular to both the magnetic field lines and the surface it passes through.
What is the direction of the induced current in a loop when there is a change in magnetic field direction?
When there is a change in the direction of the magnetic field in a loop, an induced current is generated in the loop in a direction that opposes the change in the magnetic field.
How can one determine the direction of a magnetic field using the keyword "how to find direction of magnetic field"?
To determine the direction of a magnetic field, you can use the right-hand rule. Point your thumb in the direction of the current flow and curl your fingers. The direction your fingers curl represents the direction of the magnetic field.
How can one determine the direction of a magnetic field?
To determine the direction of a magnetic field, you can use a compass. The needle of the compass will align itself with the magnetic field lines, pointing towards the direction of the field.
Why is the field left energized during dynamic braking?
the field is left energized in order that the motor behave like a generator producing an magnetic field in the opposed direction of rotation
