Whether the statement ‘The magnetic field is largest where the field lines are closest.’ is true or false.
Answer to Problem 1RQ
True.
Explanation of Solution
Magnetic fields can be represented using diagrams which are similar to those used for electric fields. The direction of the field is indicated by lines. Closeness of the field lines is proportional to the strength of the field. The field will be weak when the field lines are far way. Similarly, the field will be stronger where the field lines are closer.
Magnetic field lines are always directed from the North Pole to the South Pole outside a magnet. They are continuous loops without a beginning or ending. The direction of the field at a particular point will be tangential to the field line at that point. Two magnetic field lines never intercept each other.
Conclusion:
Thus, the statement ‘the magnetic field is largest where the field lines are closest’ is true.
