a) The magnetic field is a certain region varies with time given by B(t) =30e^ -2t in Tesla. A 10cm * 15cm rectangular coil whose plane is perpendicular to the direction of the magnetic is placed in this field, find the magnetic flux as a function of time flux(t). b) A coil consists of 200 turns of wire. Each turn is a square of side d=18cm, and a uniform magnetic field directed perpendicular to the plane of the coil is...

A generator uses a coil that has 60 turns and a 0.50-T magnetic field. The frequency of this generator is 60.0 Hz, and its emf has an rms value of 120 V. Assuming that each turn of the coil is a square (an approximation), determine the length of the wire from which the coil is made.

Just part B and C
In-class problem A coil consists of 200 turns of wire. Each turn is a square of side d = 18 cm, and a uniform magnetic field directed perpendicular to the plane of the coil is turned on. The figure shows the behavior of the magnitude of the magnetic field with time. From 1=0 to 1=0.80 s, the field changes linearly from 0 to 0.50 T. After 1 = 0.80 s, the magnitude of the field...

A square coil of wire of side 2.90 cm is placed in a uniform magnetic field of magnitude 2.25 T directed into the page as in the figure shown below. The coil has 21.5 turns and a resistance of 0.780 Ω. If the coil is rotated through an angle of 90.0° about the horizontal axis shown in 0.335 s, find the following. A square coil is shown in the plane of the page, and inside the coil a magnetic field...
A magnetic field is perpendicular to the plane of a single-turn circular coil. The magnitude of...
A magnetic field is perpendicular to the plane of a single-turn circular coil. The magnitude of the field is changing, so that an emf of 0.26 V and a current of 4.9 A are induced in the coil. The wire is then re-formed into a single-turn square coil, which is used in the same magnetic field (again perpendicular to the plane of the coil and with a magnitude changing at the same rate). What (a) emf and (b) current are...

A circular coil of wire with radius 2 cm and 60 turns is placed in a uniform magnetic field of magnitude 0.8 T. The magnetic field is parallel to the area vector; i.e. perpendicular to the plane of the coil. a) What is the magnetic flux through the coil? b) The magnetic field is decreased to 0 T in 0.1 s. What is the magnitude of the emf induced in the coil during this time interval? c) If the coil...

A magnetic field is perpendicular to the plane of a single-turn circular coil. The magnitude of the field is changing, so that an emf of 0.61 V and a current of 3.2 A are induced in the coil. The wire is the re-formed into a single-turn square coil, which is used in the same magnetic field (again perpendicular to the plane of the coil and with a magnitude changing at the same rate). What emf and current are induced in...
