foil • Sun dried lanzones peelings • Commercial mosquito coil • Mortar and pestle • Basin/containers • Food coloring • Alcohol Procedure: 1. Make sure the lanzones peelings were sun dried for a few days. 2. When fully dried‚ pulverize using a mortar and pestle. 3. Mix an equal amount of starch and pulverized lanzones peelings. 4. Add water to make a paste-like consistency. Mix thoroughly. 5. Now‚ get the commercial mosquito coil and with the foil‚ make a mold. 6. Pour the mixed starch

essentially consists of a coil as an armature‚ a split ring commutator for changing the direction of the current in the coil. There are two brushes linked with the split rings that maintain the contact with the armature for the current flow. Electric motor converts electrical energy to mechanical energy.A number of such loops form a coil and the coil is termed solenoid. If there is a soft iron core in the solenoid‚ it behaves like a magnet as long as there is current through the coil. Thus it is an electromagnet

114 Faraday’s Law of Induction Stephanie Scott Section: 10849 Group #3 Bochao Li 3/31/15 Abstract: The objective of the Faraday’s Law of Induction lab was to verify Faraday’s law of induction by measuring the emf generated in a small coil and comparing it with the calculated value. Secondly the goal was to investigate the relationship between the emf and the frequency of the driving signal. The magnetic field was found to be uniform throughout. For the frequency of 40 Hz‚ the average

Form a coil by wrapping the wire around a large test tube‚ leaving about 7 cm straight for a handle. Stretch the coil a little so there is some space between the loops. Weigh the copper coil to the nearest 0.01 g and record in your data table. 2. We Labeled a clean and dry 250 ml beaker. Weigh the beaker to the nearest 0.01 g. 3. Weigh the vial
