Sponsors and Collaborators: Chughtai Public Library (CPL), Lahore Registration: Registration is required. Date: November 16, 2024 Time: 3:00 PM - 5:00 PM Venue: Chughtai Public Library (CPL), Canal Park Gulberg 2, Lahore Abstract: Khwarizmi Science Society (KSS), Pakistan recently added the Magnetism Show to its repertoire by demonstrating it for the first time on November 16 at Chughtai Public Library (CPL), Canal Park Gulberg 2, Lahore. This show was curated by our science demonstrator Muhammad Hanzala, who pieced together the workshop incorporating fundamental concepts regarding Magnetism. Demonstrations conducted:
Description:The Magnetism Show began by sharing the intriguing story of accidental discovery of magnets by the Greek shepherd Magnes.
This discussion then shifted towards gaining knowledge on multiple aspects such as What are Magnets? How Magnets Work? Where are magnets found? and other such questions inciting children's curiosity and healthy discussions. After the young scientists had familiarized themselves with magnets through safe hands-on experiments of attraction and repulsion we reinforced their concepts regarding magnetic fields with our first experiment which was the representation of Magnetic Field Lines using iron filings.
After explaining the concept of magnets and magnetic field lines, the discussion started on how our planet Earth also creates a giant magnetic field creating the magnetic North and South poles on Earth. This led to our next group activity "Creating a Magnetic Compass." All compasses worked perfectly and pointed north to acceptable accuracy. This experiment highlighted how magnetic materials can be magnetized temporarily, and how they are influenced by the Earth’s magnetic field.
The next portion of the show drew inspiration from the famous comic book character “Venom” to create a Ferro-Fluid which was a viscous black liquid that moved in response to magnetic fields. The students actively participated in this experiment by moving the magnet near the petri dish containing the ferro-fluid and observing the ‘spikes’ on the Ferro-Fluid.
The time between experiments was utilized to create a friendly environment by quizzing the students on the material that had been covered. The second half of the session involved two major exciting activities, first one was demonstration of the Lenz's Law. For this a set of magnets was passed through the copper pipe which lessened its speed of falling from notably roughly from 2 seconds to 5 seconds! This left observers in awe and spiked another set of dialogue on how and why this happened! The star of the show came at last! Quantum Levitation! Utilizing limited resources, KSS Team levitated a superconductor over a magnetic source and wowed every observer!
