Text Solution

AI Generated Solution

To solve the question, "A free floating magnetic needle at North pole is __________ to the surface of earth," we need to analyze the behavior of a magnetic needle when it is placed at the North Pole of the Earth. ### Step-by-Step Solution: 1. **Understanding the Magnetic Needle**: A magnetic needle is a small magnet that has a North Pole and a South Pole. When it is free to rotate, it will align itself with the Earth's magnetic field. 2. **Earth's Magnetic Field at the North Pole**: At the North Pole, the Earth's magnetic field lines are directed vertically downwards. This means that the magnetic field is pointing into the Earth. ...

A magnetic needle free to rotate in a horizontal plane is placed at the centre of a circular current-carrying coil whose axis is perpendicular to the magnetic meridian at that place. It is also known that the magnetic declination at this place is zero and in this condition, the magnetic needle is pointing towards conditions, the magnetic needle is pointing towards the north-west. Now, if we reverse the direction of current in the coil, then the magnetic needle will
