Increasing the number of turns increases the magnetic field strength because more loops mean a greater concentration of the field. Related Questions: Can two magnetic field lines intersect each other? Justify your answer. A freely suspended magnet always points along the north-south direction. Why? What is the neutral zone or field-free region of the magnetic … Read more
Magnets help create rotational motion by interacting with current-carrying conductors, converting electrical energy into mechanical energy. Related Questions: Can two magnetic field lines intersect each other? Justify your answer. A freely suspended magnet always points along the north-south direction. Why? What is the neutral zone or field-free region of the magnetic field? Is there any … Read more
Each piece becomes a smaller magnet with both a north and south pole, meaning monopoles cannot exist. Related Questions: Can two magnetic field lines intersect each other? Justify your answer. A freely suspended magnet always points along the north-south direction. Why? What is the neutral zone or field-free region of the magnetic field? Is there … Read more
Soft iron is used because it has high magnetic permeability, can be easily magnetized, and loses its magnetism quickly when the current is switched off. Related Questions: Can two magnetic field lines intersect each other? Justify your answer. A freely suspended magnet always points along the north-south direction. Why? What is the neutral zone or … Read more
A solenoid produces a strong magnetic field because the current in each loop adds up, creating a concentrated and uniform field inside the coil. Related Questions: Can two magnetic field lines intersect each other? Justify your answer. A freely suspended magnet always points along the north-south direction. Why? What is the neutral zone or field-free … Read more
Magnetic Field of a Bar Magnet: A bar magnet is a permanent magnet that generates a magnetic field around it. The magnetic field of a bar magnet can be described as follows: Magnetic Poles: A bar magnet has two poles—north (N) and south (S). The magnetic field lines emerge from the north pole and enter … Read more
The strength of the magnetic field of an electromagnet depends on the following factors: Current (I): The strength of the magnetic field is directly proportional to the electric current flowing through the coil. Higher current generates a stronger magnetic field. Number of Turns in the Coil (N): The magnetic field strength increases with the number … Read more
Property Paramagnetic Materials Ferromagnetic Materials Magnetic Moment Have weak, temporary magnetic moments. Have strong, permanent magnetic moments. Response to Magnetic Field Weakly attracted to an external magnetic field. Strongly attracted to an external magnetic field. Alignment of Magnetic Dipoles Magnetic dipoles align with the external field, but only weakly. Magnetic dipoles align strongly with the … Read more
The Earth’s geographical and magnetic axes are not coincident because they are determined by different processes and are not aligned with each other. Here’s an explanation: Geographical Axis: The geographical axis is the line running from the North Pole to the South Pole, and it is defined by Earth’s rotation. It is the axis around … Read more
The Earth spins about its geographical axis instead of its magnetic axis because the geographical axis is the axis around which the Earth’s rotation is established. This axis runs from the North Pole to the South Pole and is aligned with Earth’s angular momentum. Here’s why: Geographical Axis and Earth’s Rotation: The Earth’s rotation is … Read more
