4. A charged particle is projected into a uniform B-field. Its velocity vector is perpendicular to the B-field vector. What type of path will the particle travel? Neglect gravity A flexible coil 25 cm long is shaped into a circle with its face perpendicular to a 0.25 T magnetic field. If the coil is then pulled to collapse the area in 2.0 ms, what emf is induced in the coil? 5. A car antenna is 1.5 m long. The car...
can i get the right solution please Question 1: (25 marks) A ring of steel has an external diameter of 24cm and a square cross section of 3cm by 3cm, as she m, as shown in Figure 1. A gap of 3mm exists on the ring. A copper bar of 18cm x 3cm x 3cm is fitted inside Titted inside and across the ring with negligible gap. Account for fringing by using the effective area of the air approximated by:...
i need help with #2,5, and 6 please! A Rectangula Flux in Rotating Loop 25+ 56 A rectangular loop rotates with a constant angular velocity about an axis as shown.
