Answer:
−1.9 × 10−5 Wb
Explanation:
Magnetic flux is the product of average magnetic field times the perpendicular area that is crosses times the angle between planar area and magnetic flux
Finding the area
Area = πr² = 3.14*0.075*0.075
Area=0.01767 m²
Magnetic flux = 0.01767*0.00110*cos 0
Magnetic flux =0.000019 = −1.9 × 10−5 Wb
Answer:
Commensalism
Explanation:
Commensalism is one example of the behavior of a goby and shark.
Answer
current density is given by
where J = σ E
now,
a) Electric field strength at the inner surface of an iron cylinder
a = 0.5 cm = 0.005 m b = 2.3 = 0.023
L = 10 cm = 0.1 m I = 27 A
E = 8.59 x 10⁻⁴ V/m
b) Electric field strength at the outer surface of an iron cylinder
a = 0.5 cm = 0.005 m b = 2.3 = 0.023
L = 10 cm = 0.1 m I = 27 A
E =1.87 x 10⁻⁴ V/m

Answer:
False
Explanation:
The direction of magnetic field on a current carrying conductor can be determined by the Fleming's right hand rule where
- The thumb represents the direction of motion
- the index finger represents the direction of field.
- The middle finger is the direction of induced current.
When two conductors carrying currents flowing in opposite direction, the magnetic field will be in the same direction hence they will repel.
<u><em>When the currents in them flow in same direction, then it means the magnetic field will be opposition and there will be a force of attraction between the conductors.</em></u>
