What do you mean by magnetic field? State the characteristics of magnetic field lines.
Answers
Magnetic Field:
Magnetic fields can be pictorially represented by magnetic field lines, the properties of which are as follows: The field is tangent to the magnetic field line. Field strength is proportional to the line density. Field lines cannot cross. Field lines are continuous loops.
Characteristics of Magnetic Field:
• They seek the path of least resistance between opposite magnetic poles.
• They never cross one another.
• They all have the same strength.
• Their density decreases (they spread out) when they move from an area of higher permeability to an area of lower permeability.
Hope it's helpful... ^_^
Answer:
aA magnetic field is a vector field that describes the magnetic influence on moving electric charges , electric currents and magnetic materials .A permanent magnet 's magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels the magnets
