There are theories around that some birds can actually detect magnetic fields, which they use to navigate on long migrations.

Fluctuations in the magnetic field cause the Magnetic North Pole to constantly move in an irregular path around its average position. The position of where the Magnetic North Pole is given each year is actually an AVERAGE position, as the Magnetic Pole can move around up to 80 Km or more if the magnetic field is disturbed. One of the best links to predict where the North Magnetic Pole MAY be is the Woods Hole Marine Magnetism Group link attached.
Usually, "He's kidding around with you", or, "He's lying to you"......Unless of course, he's really pulling your leg...Just joking around and trying to mess with someoneThey're pulling on your leg means they're just joking around with you. Almost as if someone is teasing you.
The area around a magnet where its magnetic force is felt is called the magnetic field.
Yes, a magnetic field exists around every object that has a magnetic property.
the area of magnetic force around a magnet is called the magnetic field
A bar magnet interacts with the magnetic field around it by creating a magnetic force that attracts or repels other magnets or magnetic materials. The magnetic field around the bar magnet is strongest at the poles and weaker in between, causing magnetic materials to align with the field.
A Magnetic Force
The magnitude of the magnetic field around a permanent magnet is greatest at the poles of the magnet. This is where the magnetic field lines are most concentrated and where the magnetic force is strongest.
Magnetic field
They are called the magnetic field lines.
