The flow of current in a circular wire creates a magnetic field at its centre. How can existence
of this field be detected? State the rule which helps to predict the direction of magnetic field.
Answers
Answer:
Explanation:
The flow of current in a circular wire creates a magnetic field at its centre. ... The existence of this field can be detected by using a magnetic compass needle. The direction of magnetic field is predicted by using Maxwell's right hand thumb rule.
The direction of magnetic field is predicted by using Maxwell's right hand thumb rule. It states that if you hold a current-carrying conductor in right hand, such that the thumb points in the direction of electric current, then the direction in which fingers encircle, gives the direction of magnetic field.
Answer:
The correct answer of this question is Maxwell's right hand thumb rule is used to forecast the direction of the magnetic field.
Explanation:
Given - The flow of current in a circular wire creates a magnetic field at its centre.
To Find - How can existence of this field be detected?
A magnetic field is created in the centre of a circular wire by the flow of current. A magnetic compass needle can be used to identify the presence of this field. Maxwell's right hand thumb rule is used to forecast the direction of the magnetic field.
Maxwell's right hand thumb rule is used to forecast the direction of the magnetic field. It is stated that and hold a current-carrying conductor in the right hand so that the thumb points in the direction of electric current, then the direction in which fingers surround gives the magnetic field direction.
