Introduction

Pen Stand is a simple toy, which helps us observe magnetism and understand magnetic levitation. Here, its enjoyment is increased further by placing a coloured fan on top to aid in its spinning!

Video Overview

    • Handle the scissor with care

    • Make sure you don’t pinch yourself with the cutting plier

    • Be careful while bending the spoke; it may pain your fingers and hands doing it, but do not try to bend it with your teeth!

  1. You need to make 2 bends in the spoke assembly. Although possible and a lot of fun with bare hands, you may also use cutting pliers to make the bends to make the job easier Leaving about 1cm after the given bend that looks like a clip, bend the spoke at a right angle; the result should look something like a lamp post Leaving about 1cm after the given bend that looks like a clip, bend the spoke at a right angle; the result should look something like a lamp post

  2. At the bottom of your spoke is an  'L'  bend, halfway down the length of the bend, bend again by 90⁰, on the same parallel plane  as the previous bend. This final bend completes your stand.

  3. Take a piece of tape, and stick the spoke on the CD such that the last bend creates the base and the first bend forms the top, like a lamp post. Make sure that the only surface directly under the lamp post is that of the CD itself

    • Make sure that the only surface directly under the lamp post is that of the CD itself

  4. Place one ring magnet on the top or the underside of the bend at the top of the stand
    • Place one ring magnet on the top or the underside of the bend at the top of the stand

  5. Take a piece of paper and fold it 4-5 times Place the paper on the pen and then slide down your magnet. The paper serves as packing and your magnet should stay firmly in position now. You may need to increase/decrease the number of folds.

    • You may need to increase/decrease the number of folds.

  6. Take off the pen cap and place the pen on the CD directly under the magnet on the top. Your pen should now be standing on its own; you now have a vertically levitating pen stand! You can give the pen a bit of a twirl, and it should keep spinning for quite some time….. Take off the pen cap and place the pen on the CD directly under the magnet on the top.

  7. Cut a piece of cardboard exactly to the shape and size of the colour-square sticker given. Stick the colour-square to your cardboard piece Cut and fold the colour-square, as indicated by the dotted and solid line. Put the piece of double-sided tape under the colour-square and stick this to the top of the pen
    • Cut a piece of cardboard exactly to the shape and size of the colour-square sticker given. Stick the colour-square to your cardboard piece

    • Cut and fold the colour-square, as indicated by the dotted and solid line.

    • Put the piece of double-sided tape under the colour-square and stick this to the top of the pen

    • Ensure that the pen continues to levitate and that the colour-square doesn't interfere with the rotation of the pen by hitting the stand

    • Place the pen stand under a ceiling fan, turned on to maximum, and enjoy the spinning levitating pen stand with a Newton disc!

    • If a fan is unavailable, or if there is no electricity, you may blow from the top as well to have your spinning pen!

    • The top bend is not parallel to the ground, thereby creating an angular orientation of the magnet

    • Magnets not orientated correctly, i.e. repelling each other rather than attracting

    • Too much gap between the magnets, thereby causing the pen to fall. Note: If your magnet is above the bend at the top try shifting it under

    • Too little gap between the magnets, thereby causing the pen to get joined to the top magnet. Note: If your magnet is under the bend at the top shift it above.

    • Magnet on the pen not placed firmly enough, thereby causing its position to change

    • Stand not taped firmly enough to the CD

    • Colour-square not folded or cut correctly

    • Colour-square folds too big, thereby hitting the stand and interfering with the spin.

  8. Spin your pen and simultaneously start a stop watch. Does spinning the pen increase or decrease the stability of the pen? Try to move the magnet to the maximum and minimum point you can before the pen goes up and sticks. Measure this.

    • Does spinning the pen increase or decrease the stability of the pen?

    • Try to move the magnet to the maximum and minimum point you can before the pen goes up and sticks. Measure this.

    • Now slip the magnet down to the max you can before the pen falls. Measure this.

    • Try sliding the pen tip to create a tilt. What is the max distance you can push it?

    • Measure the angle between the base and the pen by placing a protractor in front of it.

  9. Variation 1: By changing magnets. Variation 2: By replacing the pen. Variation 3: By using multiple pens.
    • Variation 1: By changing magnets.

    • Variation 2: By replacing the pen.

    • Variation 3: By using multiple pens.

    • Variation 4 :Changing the base.
