Ram brought a magnet near 3 pins made up of different materials. Pins Y and Z get attracted whereas pin X remains at its place as shown below.

Then X,Y,Z are _________,________,__________ respectively.

• A. Pix X - Steel
  Pin Y - Nickel
  Pin Z - Aluminium
• B. Pix X - Copper
  Pin Y - Iron
  Pin Z - Steel
• C. Pix X - Copper
  Pin Y - Brass
  Pin Z - Cobalt
• D. Pix X - Iron
  Pin Y - Copper
  Pin Z - Brass

Answer 1

The correct option is B

Pix X - Copper
Pin Y - Iron
Pin Z - Steel

When a magnet is brought close to a group of objects, the ones that are attracted are magnetic materials whereas the ones that aren't attracted are non-magnetic materials.

So we can say: pin X is non-magnetic material as it is not attracted by the magnet. It can be copper. Pin Y and pin Z are attracted by the magnet, so they are magnetic materials like iron, nickel, cobalt, steel etc.
