An investigation was conducted to find the effect of current passing through the wires of the homopolar motor and the time taken to complete one rotation. The student proposed the following hypothesis : As the magnetic field intensity around wire of homopolar motor increases the time taken to complete one rotation also increases. Student records the following data table.Sr No. Magnetic field Intensity (mili tesla) Mean Time for rotation (s)1 50202 150153 200124 25085 3006   Q 1.1Accurately interpret data and outline results using correct scientific reasoning.

Mrs. Peterson assigned the students in her class a project to design a simple electric motor. Each student had to use a permanent magnet and an electromagnet made up of a coil of wire wrapped around an iron core. To be successful, the motor had to spin at least 150 times per minute. After the students designed their motors, each motor was connected to the same voltage source, and the number of turns the motor made in 5 seconds was counted. The table below describes each student's motor.Electric Motor DesignsStudent Name Number of Turnsin the Electromagnet'sWire Coil Material of the Wire Coil Thickness of the Wire Used in the Coil Rate at Which the Motor SpinsLupe 15 copper 0.4 mm 17 turns in5 secondsSanjay 5 aluminum 0.4 mm 4 turns in5 secondsOliver 5 copper 1.2 mm 21 turns in5 secondsRebekah 15 aluminum 1.2 mm 11 turns in5 secondsFelipe 15 aluminum 0.4 mm 7 turns in5 secondsWhich students met the criteria for success?
