check this question in vi physics, fun with magnets. it comes by test generator.
the answer given is wrong, plz rectify
Use the following information to answer the next question.
The given figure shows a neutral iron ball suspended in air. When an object labelled as X is brought near the ball, it moves toward it. This is shown in the given figure.
It can be concluded from the given observation that the object X is
an iron bar
a piece of wood
an electrically charged rod
A magnet attracts magnetic materials. Iron ball is a magnetic material and so, the magnet can attract it. Hence, object X is a magnet.
The correct answer is B.
Why alternative A is wrong:
A pencil is made up of wood. Wood cannot attract an uncharged iron ball.
Why alternative C is wrong:
An iron bar cannot attract a neutral iron ball.
Why alternative D is wrong:
