Earth's crust is the right answer
Magnetic Field due to Current in a Solenoid
A Solenoid is a long coil containing right number of close tens of insulated Copper wire.
The Magnetic field produced by a current carrying solenoid is Similar to the magnetic field produced by a bar magnet.
The Strength of magnetic field produced by a current carrying conductor is directly proportional to number of coils and Strength of the Current in the solenoid. it is also depends on nature of core material.
When a current carrying conductor is placed in a magnetic force, or field. A Magnetic force is exerted on the conductor which makes the conductor move.
The Magnetic force acting on a Conductor wire is proportional to the electric current, Magnetic field of a magnet and the length of wire remaining in the magnetic field.
The Direction of force acting on a current carrying conductor in a magnetic field. Electromagnet are used in cranes to lift heavy objects .
Force maximum on a conductor when it is parallel to the magnetic field.
Direction of force can be defined by using Fleming Left Hand rule.
Tesla is the unit of magnetic field .
Additional Information
- Fleming Left Hand Rule
According to this rule when we stretch thumb for finger and middle finger of left such that they are mutually perpendicular to each other if the First finger points in the direction of the magnetic field and Second finger in the direction of current then the Thumb will be point in the direction of force acting on a conductor .
- Magnet Description
A Magnet is a simple device which attract magnetic substance like Iron Nickel and Cobalt. This term is taken from Greek word which means to attract, it is also called leading stone or load stone because it tells the direction of North and South.⠀⠀⠀⠀⠀⠀⠀
